Description

'HYDROXYPHENYLTRIAZINES' Hydroxyphenyl Riazines The invention relates to new compounds of the hydroxyphenyl-rs-triazine type, which contain a blocked o-hydroxyl group and two free o-hydroxyl groups, for use in the stabilization of organic material, especially in plastics, materials for coatings, cosmetic preparations, lotions for sunscreens or photographic material, against damage caused by light, oxygen and / or heat, and to the correspondingly stabilized organic material. When it is desired to increase the stability of an organic material, especially a coating, against light, it is usual to add a light stabilizer. One class of light stabilizers used very often are the UV absorbers, which protect the material by absorbing the harmful radiation by means of the chromophores. A major group of UV absorbers are the triphenyl-s-triazines, as described, among others, in US-A-3 118 887, US-A-3 242 175, US-A-3 244 708, GB. -A 1 321 561, EP-A-0 434 608, US-A-4 619 956, US-A-3 564 749, US-A-5 461 151, EP-A-0 704 437 and WO-96 / 28431 Individual compounds of the hydroxyphenyl-s-riazine type are also known, some of which have hydroxyl groups in the ortho position which are blocked (US-3 113 940, US-3 113 941, US-3 113 942, GB- A-975966, US-A-3249608, US-A-5597854, WO-94/05645).

Other methods of preparation of the starting compounds of formula A are described by Cousin and Volmar , Bull. Soc.

Chim. Fr. 15, 414-421 (1914), US-A-3113942 or EP-A-648753; according to or by analogy to these methods it is possible to trimerize 3 equivalents of a 2-hydroxybenzonitrile of formula B or of a 2-hydroxybenzamide of formula C (C) at elevated temperature, usually in the range 180-260 ° C, to give the compound of formula A. This route is particularly suitable for compounds of formula A in which R2 is not OH or 0R3. A particularly preferred starting compound of formula A is tris (2,4-dihydroxyphenyl) -l, 3, 5-triazine; the novel compounds obtainable therefrom by the preparation methods indicated below correspond to formula II in which R2 is -OR3 and RX1 is hydrogen. As options for the subsequent reaction of the compound of formula A for the preparation of the compound of formula I, and especially of formula II, the following possibilities can be mentioned: a) Staged reaction of free OH groups with halides or sulphates It takes place using for each OH that reacts, approximately one equivalent of a Rx-Hal reagent in which Hal is a halogen atom, preferably Cl, and Rx has the meanings given in connection with formula I above, together with approximately one equivalent of the base.

Rx-Hal can also be a mixture of reagents. Instead of the halide Rx-Hal it is also possible to use one equivalent of a sulphate (1/2 Rx-0-S02-0-Rx). If you intend to enter not only the radical -Rx but also another different radical (R2 in the meaning of -0R3) then it is convenient first to carry out the reaction with the necessary number of equivalents of R3-Hal, where R3 has the meanings given for R? / And the base and then the reaction with an equivalent of Rx-Hal. The reaction is preferably carried out in an organic solvent, for example an aromatic or aliphatic hydrocarbon, alcohol, ether, ester or amide of an appropriate boiling range; the preferred solvents are toluene, xylene, propanol, butanol, 2-methoxyethanol, 2-ethoxyethanol, diethylene glycol dimethyl ether (diglyme), dimethylformamide (DMF), dimethyl sulfoxide (DMSO). Suitable bases are organic or, preferably, inorganic bases such as hydroxides, oxides or carbonates; Important examples are hydroxides and alkali metal carbonates, such as KOH, NaOH, K2C03, Na2C03. The reaction temperature is usually in the range 80-180 ° C, preferably in the range 100-150 ° C. The reaction can also be carried out as a 2-phase reaction in the presence of phase transfer catalysts such as the tetraalkylammonium salts, for example, - in this case the halide or sulfate is normally - and especially when it is used as a pure reactive alkylation - present in the organic phase and the triazine precursor in the aqueous phase. For example, a compound of formula II, in which R.sub.2 is -0R.sub.3, can be obtained, for example, by the following reaction schemes: (cathoxide "formula A) (Formulated formula II) b) Step reaction of the free OH groups with epoxides Instead of the reagents described in a) it is also possible to use epoxides. For each OH group that reacts, approximately 1 equivalent or more than one epoxide of type O R * is used in each case together with a catalyst as such or in a solvent. This reaction normally takes place without the addition of bases. The primary reaction product of formula I or II, in which R3 or, if appropriate, R3 and Rx correspond to the formula -CH2-CH (0H) -R ', can, if desired, be subsequently reacted by methods and known, for example with etherification or esterification of the aliphatic OH group. If it is intended to introduce not only the radical -R 3 as -CH 2 -CH (OH) -R ', but also another radical other than R x, it is then convenient to first carry out the reaction with the necessary number of equivalents of Or ¿R 'where no excess is normally used and where -CH2-CH (OH) -R' has the meanings given for Rx, and then carry out the reaction with an equivalent of the other desired reagent, for example, Rx -Hal and base, or with another equivalent of O / ____. R ' Conversely, in accordance with a) it is also possible first to introduce a radical -R3 and then to react the reaction product with O / \ ' to give the compound of formula I 6 II. The ring opening of the epoxide is preferably carried out in an organic solvent, in particular in an apolar organic solvent, examples are aromatic or aliphatic hydrocarbons having an appropriate boiling range, preferably toluene, xylene, mesitylene. Examples of suitable catalysts are phase transfer catalysts, including quaternary phosphonium salts or tertiary amines; p. ex. ethyltriphenylphosphonium bromide or benzyldimethylamine. The. Reaction temperature is normally in the range of 80-200 ° C, preferably in the range 100-180 ° C. For example, a compound of formula II in which R2 is -0R3 can be obtained, for example, by the following reaction schemes: The products of the reactions described above can be further modified by methods already known within the context of the definitions given in formula I. The reactions can be carried out in the absence of oxygen, for example in a stream of an inert gas such as argon, - however, oxygen does not interfere in all cases, so that the reaction can also be carried out without taking this measure. Once the reaction is finished, the product can be finished, according to the usual methods. _. ._ The new compounds are particularly suitable for the stabilization of organic materials against damage caused by light, oxygen or heat. The new compounds are especially suitable as stabilizers against light (UV absorbers). The materials to be stabilized can be, for example, oils, fats, waxes, coating materials, cosmetics, photographic materials or biocides.

These metal complexes can be in free form or fixed on substrates, typically on activated magnesium chloride, titanium (III) chloride, alumina or silicon oxide. These catalysts can be soluble, or insoluble in the polymerization medium. The catalysts can themselves be used in the polymerization or activators, typically metal alkalis, metal hydrides, metal haloalkyls, metal oxyalkyls or metal alkyloxanes can also be used, said metals being elements of the groups Ia and / or Illa of the Periodic Table . The activators may be conveniently modified with additional ester, ether, amine or silyl ether groups.

The nature and amount of the other stabilizers added are determined by the nature of the substrate to be stabilized and by the intended use. It is usual to use 0.1-10, for example 0.2-5% by weight, based on the material to be stabilized. It is particularly advantageous to use the novel compounds in combination with sterically blocked amines, for example 2, 2, 6,6-tetraalkylpiperidine derivatives. The invention therefore encompasses a synergistic stabilizing mixture comprising (a) a compound of formula I, and (b) at least one sterically blocked amine, its salt with a desired acid or its complex with a metal, and encompasses also a composition containing A) an organic material sensitive to oxidative, thermal and / or actinic degradation, B) at least one compound of formula I, and C) a conventional additive of the amine type which is magnetically blocked .

Preferred sterically blocked amines are, for example, those indicated in the above relationship in 2.6 or those indicated above. adalaiite_- as additives - for new coating compositions. Of particular interest is the use of the compounds of formula I as stabilizers in synthetic organic polymers, and the corresponding compositions. The organic materials that are protected are preferably natural organic, semi-synthetic or synthetic materials. When cosmetic preparations are used, the organic material that is protected is normally the human or animal skin or hair. The novel stabilizer mixtures can be used with particular advantage in compositions comprising as component A a synthetic organic polymer, especially a thermoplastic polymer, a binder for coatings such as, for example, paints or photographic material. Examples of suitable thermoplastic polymers are polyolefins, especially polyethylene (PE) and polypropylene (PP), and polymers containing heteroatoms in the main chain. Examples of such polymers are the following classes of thermoplastic polymers: l. Polyacetals such as polyoxymethylene and those polyoxymethylenes containing comonomers such as ethylene oxide; polyacetals modified with thermoplastic polyurethanes, acrylates or MBS. 2. Polyphenylene oxides and sulfides, and their mixtures with styrene polymers or polyamides. 3. Polyamides and copolyamides, for example, those derived from diamines and dicarboxylic acids and / or amino carboxylic acids or the corresponding lactams such as polyamide 4, polyamide 6, polyamide 6/6, 6/10, 6/9, 6/12, 4/6, polyamide 11, polyamide 12, aromatic polyamides based on m-xylene diamine and adipic acid; polyamides prepared from hexamethylenediamine and iso- and / or terephthalic acid with or without an elastomer as a modifier, for example poly-2,4, 4-trimethylhexamethyleneterephthalamide, poly-m-phenyleneisocyta-phthalamide. Block copolymers of the aforementioned polyamides with polyolefins, olefin copolymers, ionomers or chemically bonded or grafted elastomers; or with polyethers, p. ex. with polyethylene glycol, polypropylene glycol or polytetramethylene glycol. In addition, copolyamides or polyamides modified with EPDM or ABS; and polyamides condensed during the process (RIM polyamide systems). 4. Polyureas, polyimides, polyamidoimides and polybenzimidazoles. 5. Polyesters, for example the derivatives of dicarboxylic acids and dialcohols and / or of hydroxy carboxylic acids or of the corresponding lactones, such as polyethylene terephthalate, polybutylene terephthalate, poly-1,4-dimethylolcyclohexane terephthalate, polyhydroxybenzoates, and also polyether block esters, polyether derivatives with final hydroxyl groups; and also polyesters modified with polycarbonates or MBS. 6. Polycarbonates and polyester carbonates, especially aromatic polycarbonates, for example those based on 2,2-bis (4-hydroxyphenyl) prapane or 1,1-bis (4-hydroxyphenyl) cydohexane. 7. Polysulfones, polyether sulfones and polyether ketones, especially aromatic polymers of this class. 8. Mixtures ("polyblends") of said polymers with each other or with other polymers, for example, with polyolefins, polyacrylates, polydienes or other elastomers as modifiers of impact resistance. Among these, preference is given to polycarbonates, polyesters, polyamides, polyacetals, polyphenylene oxides and polyphenylene sulfides, but especially to polycarbonates. The polycarbonates are to be understood as meaning in particular those polymers whose repeating constitutional unity is the formula [0-A-O-CO] -, in which A is a divalent phenolic radical. Examples of A are described, inter alia, in US-A-4 960 863 and DE-A-39 22 496. The polymers of component (A) can be linear or branched. The shaping of these polymers is carried out at a relatively high temperature, - the polycarbonate, for example, is injection molded at 220-330 ° C. At these temperatures, most of the usual light stabilizers and antioxidants are unstable and begin to decompose. The aforementioned mixtures are extremely stable at temperature and therefore are particularly suitable for the stabilization of the mentioned polymers.

The use in multilayer systems is also interesting. In this case a new polymer composition having a relatively high content of the new stabilizer, for example, 5-15% by weight, is applied in a thin layer (10-100 μm) to a shaped article comprising a polymer that contains little or no stabilizer of formula I. The application can take place at the same time as the shaping of the support structure, for example, by coextrusion. The application can be made, however, to the final shaped support structure, for example by rolling with a film or coating with a solution. The outer layer or layers of the finished article have the function of a UV filter that protects the interior of the article against UV light. the outer layer preferably contains 5-15% by weight, in particular 5-10% by weight, of at least one compound of formula I. The polymers stabilized in this way are notable for their high stability to inclement weather, and especially for their high resistance to UV light. As a result, even when used outdoors, they retain their mechanical properties and their color and brightness over a long period. Other particularly preferred organic materials are the coating compositions and the photographic material. The invention therefore also provides a composition in which the new compound is incorporated into a thermoplastic polymer, a film-forming binder, especially those based on an acrylic, alkyd, polyurethane, polyester or polyamide resin, or appropriately modified resins, a photographic material or a cosmetic preparation, including a hair cosmetic preparation, for example a cosmetic or a sunscreen. The material to be protected (component A) may in this case be, for example, a thermoplastic polymer, a film-forming binder, especially one based on an acrylic, alkyd, polyurethane, polyester or polyamide resin or appropriately modified resins, a photographic material, or the skin or human or animal hair. The use of the novel compounds as stabilizers for coatings, for example for paints, is of particular interest. The invention also relates to those compositions whose component A is a film-forming binder. The new coating composition preferably contains 0.01-10 parts by weight, especially 0.05-10 parts by weight, and in particular, 0.1-5 parts by weight of the new stabilizer B per 100 parts by weight of the binder solid A. Multilayer systems are also possible here, in which the concentration of the compound of formula I (component B) in the upper layer may be greater, for example from 1 to 15 parts by weight, especially 3-10 parts by weight of B per 100 parts by weight of the solid binder A. The use of the compound of formula I as a stabilizer in coatings it has as an additional advantage that the delamination is avoided, that is to say the appearance of flakes in the coating of the substrate. This advantage manifests itself in particular in the case of metal substrates, even in the case of multilayer systems on metal substrates. Suitable binders (component A) are in principle all those customary in the art, for example those described in the Ullmann Encyclopedia of Industrial Chemistry, 5th edition, vol. A18, pp 368-426, VCH, Weinheim 1991. The binder is generally a film-forming binder, based on a thermoplastic or thermosetting resin, predominantly a thermosetting resin. Examples thereof are alkyd, acrylic, polyester, phenolic, melamine, epoxy and polyurethane resin and mixtures thereof. Component A can be a cold or temperature curable binder, the addition of a curing catalyst possibly being advantageous. Examples of suitable catalysts that accelerate the curing of the binder are described in the Ullmann Encyclopedia of Industrial Chemistry, vol. A18, p. 469, VCH Verlagsgesellschaft, Weinheim 1991. Preference is given to coating compositions in which component A is a binder comprising an acrylate functional resin and a crosslinker.

Thermoplastic polyacrylate paints based on thermoplastic acrylate resin or externally crosslinked acrylate resins in combination with etherified melamine resins; Paint systems based on siloxane-modified or fluorinated-modified acrylate resins The new composition for coatings preferably contains, in addition to components A and B, as component C, a light stabilizer of the sterically blocked amine of the type 2- (2-hydroxyphenyl) -l, 3, 5-triazine and / or 2-hydroxyphenyl-2H- benzotriazole, for example, as mentioned in the previous list in sections 2.1, 2.6 and 2.8. Of particular technical interest in this context is the addition of 2-monoresorcinyl-4,6-diaryl-1,3,5-triazines and / or 2-hydroxy-phenyl-2H-benzotriazoles.

In order to achieve maximum light stability, it is particularly advantageous to add sterically blocked amines, as mentioned in the above list in 2.6. The invention therefore relates to a coating composition which, in addition to components A and B, contains as component C a light stabilizer of the sterically blocked amine type. This stabilizer is preferably a derivative of 2, 2, 6,6-tetraalkylpiperidine, which comprises at least one group of formula wherein R is hydrogen or methyl, especially hydrogen. Component C is preferably used in an amount of 0.05-5 parts by weight per 100 parts by weight of solid binder. Examples of tetraalkylpiperidine derivatives that can be used as component C are described in EP-A-356677, pages 3-17, sections a) to f). These sections of this EP-A are considered as part of the present description. It is particularly convenient to employ the following tetraalkylpiperidine derivatives: bis- (2,2,6,6-tetramethyl) piperidin-4-yl) succinate, bis- (2,2,6,6-tetramethyl) piperidin-4- il) sebacate, bis- (2,2,6, 6-pentamethyl) piperidin-4-yl) sebacate, (3, 5-di-tert-butyl-4-hydroxy-benzyl) malonate di (l, 2, 2,6,6-pentylethyl) piper idin-4-yl) butyl, bis- (1-octyloxy-2, 2,6,6-tetramethylpiperidin-4-yl) sebacate, tetra (2, 2,6,6-tetramethylpiperidin-4-yl) butan-1, 2,3,4-tetracarboxylate, tetra (1, 2,2,6,6-pentamethylpiperidin-4-yl) butan-l, 2,3, 4-tetracarboxylate, 2, 2, 4, 4-tetramethyl-7-oxa-3, 20-diaza-21-oxodiespiro [5.1.11.2] heneicosane, 8-acetyl-3-dodecyl-l, 3, 8-triaza- 7, 7, 9, 9-tetramethylpyrro [4.5] decan-2,4-dione, l, l-bis (l, 2,2,6,6-pentamethylpiperidin-4-yl-oxycarbonyl) 2- (4-methoxyphenyl) ) -ethene, or a compound of formula R R I I R-NH- (CH 2 A'3-N- (CH 2) - N- (CH 2) 3 -NH-R where R = CH3 R R CH, I 3 I I I 3 R N - (CH 2) 3 - N - (CH 2) 2 - N - (CH 2) 3 - N - R where R = twenty where m is 5-50. In addition to the components A, B, and C, when present, the coating composition may also contain other components, for example solvents, pigments, colorants, plasticizers, stabilizers, thixotropic agents, drying catalysts and / or processing aids. equalization Examples of possible components are those described in the Ullmannn Encyclopedia of Industrial Chemistry, 5th edition, vol. A18, pp. 429-471, VCH, Weinheim 1991. Possible drying catalysts or curing catalysts are, for example, organometallic compounds, amines, resins containing amino and / or phosphine groups. Examples of organometallic compounds are metal carboxylates, especially those of the metals Pb, Mn, Co, Zn, Zr or Cu, or 3 metal chelates, especially those of the metals Al, Ti or Zr, or organometallic compounds such as organotin compounds. , for example. Examples of metal carboxylates are the stearates of Pb, Mn or Zn, the octoates of Co, Zn or Cu, the naphthenates of Mn and Co or the corresponding linoleates, resinates or talates.

Examples of metal chelates are the chelates of aluminum, titanium or zirconium of acetylacetone, ethyl acetylacetate, salicylaldehyde, salicylaldoxime, o-hydroxy-acetophenone or ethyl trifluoroacetylacetate and the alkoxides of these metals. Examples of organotin compounds are dibutyltin oxide, dibutyltin dilaurate or dibutyltin dioctoate. Examples of amines are, in particular, tertiary amines, for example, tributylamine, triethanolamine, N-methyldiethanol-amine, N-dimethylethanolamine, N-ethylmorpholine, N-methylmorpholine or diazabicyclooctane (triethylenediamine) and their salts. Other examples are the quaternary ammonium salts, for example trimethylbenzylammonium chloride. The resins containing amino groups are simultaneously binders and curing catalysts. Examples thereof are acrylate copolymers containing amino groups. The phosphines, for example triphenylphosphine can also be used as a curing catalyst. The new coating compositions can also be radiation curable coating compositions. In this case, the binder consists essentially of monomeric or oligomeric compounds having ethylenically unsaturated bonds (prepolymers), which after the application, are cured, that is, converted into a high molecular weight crosslinked form, by actinic radiation . When the system is a UV curing system, a photoinitiator is usually also included. Appropriate systems are described in the aforementioned Ullmann Encyclopedia of Industrial Chemistry, 5th edition, vol A18, pages 451-453. In radiation curable coating compositions, the new stabilizers can be used even without the addition of sterically blocked amines. The new coating compositions can be applied to any desired substrate, for example metals, wood, plastics or ceramic materials. In the case of automotive finishing, it is preferably used as the last coat of paint. If this final coating consists of two layers of which the lower layer is pigmented and the upper layer is not, then the new coating composition may be used, for the upper layer or the lower layer or for both layers, but preferably for the top layer. The new coating compositions can be applied to the substrates by the usual techniques, for example brush-painting, spraying, pouring, immersion or electrophoresis; see also the Ullmann Encyclopedia of Industrial Chemistry, 5th edition, vol A18, pages 491-500. Depending on the binder system, the coating can be cured at room temperature or by heating. The coating is preferably cured at 50-150 CU, and powder coatings at higher temperature. The coatings obtained according to the invention possess an extraordinary resistance to the detrimental effects of light, oxygen and temperature; Particular mention should be made of the good light stability and weathering stability of the resulting coatings, for example, of paints. Therefore, the invention also has as its object a coating, in particular a paint, which is stabilized against the damaging effects of light, oxygen and temperature, by the addition of a compound of formula I.

The paint is preferably a final coating for automobiles. The invention also has for object, a process for the stabilization of a coating based on organic polymers against damage caused by light, oxygen and / or temperature, which process comprises mixing with the coating composition of a compound of formula I , and also has as an object the use of the compounds of formula I in coating compositions as stabilizers against damage caused by light, oxygen and / or heat. The coating compositions may contain an organic solvent or a mixture of solvents in which the binder is soluble. However, the coating composition can also be an aqueous solution or dispersion. The vehicle can also be a mixture of an organic solvent and water. The coating composition can also be a system with a high solids content or it can be without any solvent (for example powder coating). -The-powder coatings are those that by. example, as described in the Ullmann Encyclopedia of Industrial Chemistry, 5th edition, A18, pages 438-444. The powder coating can also be in the form of a powder suspension, that is, a dispersion of the powder in, preferably, water. The pigments can be inorganic, organic or metallic. The new coating compositions preferably do not contain pigments and are used as clear coatings. Equally preferred is the use of a coating composition as a final finish for applications in the automotive industry, especially as a pigmented or non-pigmented final coating of the coating system. Its use for underlying coatings is, however, also possible. The new compounds of formula I are also particularly suitable as UV filters for the protection of the skin and hair of humans and animals against the harmful action of UV radiation. These compounds are therefore suitable as light stabilizers in cosmetic, pharmaceutical and veterinary preparations. These compounds can be used either in solution or in the micronized state. Therefore, the subject of the invention is also a cosmetic preparation containing at least one compound of formula I and cosmetically compatible excipients or excipients. For the use in eosmetry, the new stabilizers against light, when they are not dissolved, normally have an average particle size in the range of 0.02 to 2, preferably 0.05. to 1.5, and with particular preference, from 0.1 to 1.0 μ The new insoluble UV absorbers can be prepared with the appropriate particle size by customary methods, for example by milling with for example a mill The jetting is preferably carried out in the presence of 0.1 to 30, preferably 0.5 to 15% by weight, based on the UV absorber, of an auxiliary milling such as, for example, an alkylated vinylpyrrolidone polymer, a vinylpyrrolidone-vinyl acetate copolymer, an acyl glutamate or, in particular, a phospholipid In addition to the new UV absorbers, the cosmetic compositions may also contain one or more different protection agents front to UV rays, for example triazines, oxanilides, triazoles or amides or cinnamides containing vinyl groups. Said protectors are described, for example, in GB-A-2,286,774 or are included in Cosmetics & Toiletries (107), 50 ff (1992). The new cosmetic compositions contain from 0.1 to 5, for example from 0.1 to 15, especially from 0.5 to 10% by weight, based on the total weight of the composition, of a UV absorber or a mixture of UV absorbers and a cosmetically compatible auxiliary.

The cosmetic compositions can be prepared by physically mixing the absorber or UV absorbers with the auxiliary product by customary methods., - for example by simple joint agitation of the individual components. The new cosmetic compositions can be formulated as a water-in-oil or oil-in-water emulsion, as an oil-in-alcohol lotion, as a vesicular dispersion of an ionic or non-ionic amphiphilic lipid, as a gel, as a pencil solid or an aerosol formulation. As a water-in-oil or oil-in-water emulsion, the cosmetically compatible auxiliary preferably contains from 5 to 50% of an oil phase, from 5 to 20% of an emulsifier and from 30 to 90% of water. The oil phase in this case can be any suitable oil for cosmetic formulations, for example one or more hydrocarbon oils, a wax, a natural oil, a silicone oil, a fatty acid ester or a fatty alcohol. The monooles and polyols are ethanol, isopropanol, propylene glycol, hexylene glycol, glycerin and sorbitol. The cosmetic compositions for the hair may be - in the form of a shampoo, lotion, gel or emulsion for rinsing, before or after washing with shampoo, before or after dyeing or bleaching, before or after the permanent waving or before or after the operation of straightening, - in the form of a lotion, a foam or a gel for combing or treating, - in the form of a lotion or a gel for brushing or rolling, - in the form of a hair spray, - in the form of a composition for the permanent wavy or for the smoothing, for the dyeing or discoloration of the hair. For example, the following hair cosmetic formulations can be employed: to a spontaneously emulsifying stock formulation, consisting of the UV absorber, PEG-6-C10 oxo alcohol and sorbitan sesquioleate, to which water and any a desired quaternary ammonium compound, for example, 4% minkamidopropyl-dimethyl-2-hydroxyethylammonium chloride or quaternium 80; a2) a stock formulation, which spontaneously emulsifies, consisting of the UV absorber, tributyl citrate and PEG-20-sorbitan monooleate, to which water and any desired quaternary ammonium compound is added, for example chloride minkamidopropyl-dimethyl-2-hydroxyethylammonium 4% or quaternium 80; b) solutions of the UV absorber in butyltriglycol and tributyl citrate, with the addition of a quaternary ammonium; c) dispersions of micronized UV absorbers obtained by known methods (precipitation of solutions or mixed solutions, grinding), with an average diameter of 0.05-1.0 mm in APG (e.g.

Plantaren) and a quaternary ammonium (eg, minkamidopropyl dimethyl-2-hydroxyethylammonium chloride) in an aqueous formulation; - d) mixtures or solutions of the UV absorber with n-alkylpyrrolidone. The cosmetic compositions may also include other components, such as p. ex. emollients, emulsion stabilizers, skin moisturizers, tanning accelerators, thickeners such as xanthan, moisture retention agents such as glycerin, preservatives, flavorings and colorants. The new cosmetic formulations are an excellent protection of human skin and hair against the harmful influence of sunlight. Other materials that are stabilized with the new compositions are the recording materials. Such materials are understood, for example, as described in Research Disclosure 1990, 31429 (pages 474-480) for photographic reproduction and other reprographic techniques. The new recording materials include, for example, pressure-sensitive copying systems, photocopiers with microcapsules, heat-sensitive copying systems, photographic material and ink-jet printing. The new registration materials present an unexpectedly high quality, especially with regard to their stability to light.

The new registration materials have a structure that is already known, which corresponds to its usefulness. It consists of a support, for example a film of paper or plastic on which one or more coatings is applied. Depending on the type of material, these coatings contain the necessary components, in the case of photographic material, for example silver halide emulsions, dye couplers, dyes and the like. The material provided especially for ink jet printing has a usual support on which there is an absorption layer for the ink. Uncoated paper can also be used for inkjet printing, - in this case the paper functions simultaneously as a support and has the absorbent for the ink. A suitable material for inkjet printing is described, among others, in the U.S. Pat. No. 5,073,448, the content of which description is considered as forming part of the present description. The registration material can also be transparent, for example in the case of films for projection. The compound or compounds of formula I can be incorporated into the material even in the course of manufacturing, - in the manufacture of paper, for example, by adding it to the pulp. Another method of use is by spraying the material with an aqueous solution of the compound (s) of formula I, or by adding it to the coating. Coatings for transparent recording materials for projection should not contain any particles that diffuse light such as pigments or fillers.

Coatings attached to a color may contain other additives, for example antioxidants, light stabilizers (including UV absorbers that are not included among the new UV absorbers), viscosity improvers, brighteners, biocides or anti-static agents. The coating is usually prepared as follows: The water-soluble components, for example the binder, are dissolved in water and mixed. The solid components, for example the fillers and other additives as already described, are dispersed in this aqueous medium. The dispersion is advantageously carried out with the aid of the device, for example p. ex. ultrasonic devices, turbine agitators, homogenisers, colloid mills, pearl mills, sand mills, high speed agitators and the like. A particular advantage of the compounds of formula I is its easy incorporation to the coating. As mentioned, the new registration materials cover a wide field of employment. The compounds of formula I can be used, for example, in pressure-sensitive copying systems. They can be added to the paper to protect against light the precursors of the microencapsulated colors, or to the binder of the development layer for the protection of the colors formed therein. Photocopying systems with microcapsules sensitive to light that develop by pressure are described, among others, in the U.S. Pat. No. 4,416,966; 4,483,912; 4. 352,200; 4,535,050; 4,5365,463; 4,551,407; 4,562,137 and 4. 608,330; and also in EP-A-139,479; EP-A-162,664; EP-A-164,931; EP-A-237,024; EP-A-237,025 and EP-A-260,129. In all of these systems, the compounds of formula I can be added to - the layer re.ceptora_del color. Alternatively, the compounds of formula I can be added to the color donor layer to protect the color formers against light. The compounds of formula I can also be used in recording materials, which are based on the principle of photopolymerization, photoplastification or rupture of the microcapsules, or when using diazonium salts sensitive to temperature or photosensitive, leuco dyes with an oxidizing agent or lactones dyes with Lewis acids. The temperature-sensitive recording material exploits the reaction imparting the color between a colorless or weakly colored base dye and an organic or inorganic developer, the recorded image being produced by the heat-induced contact of the two materials. This type of temperature-sensitive recording material is very widespread not only as a means of recording for faxes, computers, etc., but also in many other fields, for example in the printing of labels. The temperature-sensitive recording material according to the present invention is composed of a support, a temperature-sensitive color-forming recording layer on this support, and optionally a protective layer on the sensitive color forming recording layer. at the temperature. The temperature-sensitive color-forming recording layer contains as its main constituent a color imparting compound and a color developing compound, and also a compound of formula (I). If said protective layer is present, the compound of formula (I) can also be incorporated into the protective layer. Heat-sensitive recording materials are described, for example, in JP-A 8-267 915. Other fields of use are registration materials for color diffusion transfer printing, thermal wax transfer printing and printing by dot matrix and for use with printers, recorders or printers of electrostatic, electrographic, electrophoretic, magnetographic and electrophotographic graphics of laser. Of the aforementioned materials, preference is given to registration materials for color diffusion transfer printing, as described, for example, in EP-A-507,734. The compounds of formula I can also be used in inks, preferably in inks for ink jet printing, for example, those described in U.S. Pat. No. 5,098,477, the content of which is considered as forming part of the present description. The invention therefore also comprises an ink comprising at least one compound of formula I as a stabilizer. The ink, especially for ink jet printing, preferably contains water. The inks contain the stabilizer of formula I usually in a concentration of 0.01 to 20% by weight, in particular 0.5 to 10% by weight.

The new recording materials, for example materials for photographic registration, also offer the advantage over the materials containing conventional UV absorbers, that the UVAs of formula (I) are necessary in a comparatively small amount, also meaning that the thickness of the The layer containing the UVA is kept low, a factor that has a positive effect, among others, on the properties of the image. Another advantage of the new stabilizers is their inherent high stability in extreme weather conditions, especially with high humidity and high temperatures. The new photographic material can be a material for black and white or for color, - photographic material for color is preferred. Examples of photographic materials for color are negative films for color, inverted films for color, positive films for color, photographic paper for color, inverted photographic paper for color, color-sensitive materials for the dye diffusion transfer process or the process of discoloration of silver dye. Examples of suitable carriers for the production of photographic materials for color are films and sheets of semi-synthetic and synthetic polymers, such as cellulose nitrate, cellulose acetate, cellulose butyrate, polystyrene, polyvinyl chloride, polyethylene terephthalate and polycarbonate, and paper laminated with a barite layer or an or-olefin polymer layer (eg polyethylene). These supports can be colored with dyes or pigments, for example titanium dioxide. They can also be colored black to serve as protection from light. The surface of the support is generally subjected to a treatment to improve the adhesion of the photographic emulsion layer, for example a corona discharge with the subsequent application of a substrate layer. The new material preferably comprises the silver halide emulsion layers in the following order from the support: blue sensitive layer, green sensitive layer and red sensitive layer. In the new photographic material for color. the UV absorber is preferably in a layer above the green sensitive layer, in particular in a layer preferably above the silver halide emulsion layer (s). The novel UV absorber is preferably present in the photographic material in an amount from 0.001 to 10 g per m2, for example from 0.1 to 8 g / m2, especially from 0.005 to 6 and, in particular, from 0, 01 to 4 g / cm2. The new photographic recording material for color is preferably a material having the following sequence of layers: a: protective layer b: intermediate layer (possible absent) c c: red-sensitive layer d d: intermediate layer e e: green sensitive layer f f: intermediate layer g g: blue sensitive layer h h: support Another example is a material that has a similar layer structure but in which layer a is absent. The novel UV absorber of formula (I), in the sequence of layers shown, is conveniently present for example in at least one of the layers ae, preferably in layer a, b, cy / od, especially in a , by / oc, and in particular in ay / or b. Preference is given to a photographic recording material containing a compound of formula (I) in a layer on top of the silver halide emulsion layer (s). Preference is also given to the photographic recording material containing at least one of each of the red-sensitive and green-sensitive halide emulsion layers, and between them, an intermediate layer, wherein at least one compound of the formula (I) is present in the intermediate layer between the red-sensitive silver halide layer and the green-sensitive layer. A very particularly preferred photographic recording material comprises at least one of each of the red-sensitive, green-sensitive and blue-sensitive silver halide emulsion layers, and also at least two intermediate layers between the aforementioned layers and one protective layer wherein at least one compound of formula is present(I) in at least one layer on top of the silver halide emulsion layer sensitive to green, and the silver halide emulsion layers contain stabilizers for dark storage and / or light stabilizers. The essential constituents of the color photographic emulsion layers are binders, silver halide particles and dye couplers. Of particular interest is, for example, a photographic recording material for color, comprising on a support, at least one layer of blue-silver-based silver halide emulsion, containing at least one yellow coupler, at least one green-sensitive silver halide emulsion layer containing at least one magenta coupler, and at least one layer of red-silver-silver halide emulsion containing at least one cyano coupler, and the usual one (s) is) top layer (s) and intermediate layer (s), at least one of the layers containing a compound of formula (I). Photographic emulsions can be spectrally sensitized using methine dyes or other dyes. Particularly suitable dyes are cyanine dyes and merocyanine dyes including complex dyes of merocyanine. In Research Disclosure 17643 (Dec. 1978) chapter IV, a summary of suitable polymethine dyes can be found as spectral sensitizers, their suitable combinations and supersensitizing combinations.

Distinctly sensitized emulsion layers are assigned to monomeric or polymeric color couplers, which may be located in the same layer or in an adjacent layer. It is common to assign cyano couplers to red-sensitive layers, magenta couplers to green-sensitive layers, and yellow couplers to blue-sensitive layers. The yellow copulators which can be used in the new material are preferably compounds of formula A: Q RrCO-CH-CO-NHR2 (A) 'in which Rx is alkyl, cycloalkyl, arylamino, anilino, a heterocycle or aryl group, R2 is aryl and Q is hydrogen or a group that can be removed by reaction with the oxidized developer. The magenta couplers can, for example, be simple l-aryl-5-pyrazolones, or pyrazole derivatives fused with 5-membered heterocyclic rings, for example the imidazo-pyrazoles, pyrazole-pyrazoles, pyrazoletriazoles or pyrazoletra-zoles. The cyano couplers can, for example, be derivatives of phenol, 1-naphthol, pyrazoloazole, pyrroloazole or of the pyrazoloquinazolone.

Other important components, especially copulators, are described in US-5,578,437. The present invention further provides a method of stabilizing the photographic recording material, which consists on a support, of at least one layer of silver halide emulsion, and if desired, of at least one intermediate layer and / or a protective layer, which method consists of the addition of a UV absorber of formula (I) to at least one of said layers. The present invention also relates to the use of compounds of formula (I) for the stabilization of the photographic recording material, which consists on a support, of at least one layer of silver halide emulsion and if desired, so less of an intermediate layer and / or a protective layer.

The preferences described above in connection with the new compounds of formula (I) are applied analogously to the new compositions, the new method and the new use. The incorporation into the organic material to be stabilized can take place, for example, by mixing or applying the compounds of formula I and any other additive by methods customary in the art. When the materials are polymers, especially synthetic polymers, the incorporation may take place before or during the shaping process, or by applying the dissolved or dispersed compound to the polymer, with or without the subsequent evaporation of the solvent. In the case of elastomers, these can also be stabilized as latexes. Another option for the incorporation of the compounds of formula I into the polymers is to add them before, during or directly after the polymerization of the corresponding monomers and / or before the crosslinking. In this context, the compounds of formula I can be added as they are or in encapsulated form (for example in waxes, oils or polymers). In the case of addition before or during polymerization, the compounds of formula I can also act as a chain length regulator of the polymers (chain terminators). The compounds of formula I can also be added in the form of a masterbatch ("a concentrate") containing this compound, for example in a concentration of 2.5 to 25% by weight, based on the polymers to be stabilized. The compounds of formula I can be suitably incorporated by the following methods: in the form of an emulsion or dispersion (eg to latexes or emulsion polymers), as a dry mixture during the mixing of additional components or polymer blends, by direct addition to the processing apparatus (eg extruders, internal mixers, etc.) in the form of solution or melt. Stabilized polymer compositions obtained in this way can be converted into shaped articles, e.g. ex. in fibers, films, tapes, sheets, sandwich boards, containers, pipes and other profiles, by the usual methods, for example, by hot pressing, spinning, extrusion or injection molding. The invention therefore also relates to the use of a new polymer composition for the production of a shaped article.
