Definitions

  • the invention relates to a pigment-containing, multilayer Recording material for ink jet printing (ink jet printing).
  • the application relates to an ink jet paper, that is waterproof and for image recording with photo quality is suitable for all common printer types.
  • the invention also relates to a method for producing a multilayer recording material for the Inkjet printing.
  • Pigments based on silicon dioxide are mostly used. But it is also known to use alumina pigments in ink-jet materials use. Compared to silica pigments are characterized by positive surface charge, which means fixation of dye particles in the ink possible is. Furthermore, they are very porous and have small particle diameters and form little agglomerates, so with that transparent layers can also be obtained, as for transparent films are required. They are manufactured so far by hydrolysis from the aluminum alkoxides, whereby Depending on the manufacturing conditions, pigments with a boehmite or Pseudoboehmite structure can be obtained.
  • the object of the invention is to provide an improved multilayer Recording material, in particular for inkjet printers provide with the disadvantages of the conventional Recording materials are overcome and in particular increased surface gloss and reduced fading which shows ink dyes on contact with water. Of the material for the most common types of printers is also said to be be suitable.
  • the object of the invention is also a Process for producing such a recording material specify.
  • the basic idea of the invention is a two or more layers Recording material with at least two color receiving layers to provide that in an upper color receiving layer at least one surface-modified, pyrogenic Alumina pigment and in a lower-lying color receiving layer contains at least one silica pigment.
  • the material according to the invention is rather suitable for the common printer types.
  • the Material preferably contains two different ones in the lower layer, surface modified silica pigments, polymers Color fixatives and plasticizers and in the top layer the surface modified alumina pigment.
  • the fumed alumina pigment used in the present invention encompasses flame-pyrolytically produced aluminum oxide particles. These have the advantages of reduced interactions with other layer components and inexpensive production.
  • the invention also relates to a method for the production of said recording material.
  • application solutions with the compositions described provided and applied to a carrier material. Subsequently drying takes place.
  • the coating of the carrier material is preferably carried out in a manner known per se using an extrusion caster, starting with the application of the lower layer and then on the pre-dried underlayer the upper sublayer is placed. But it is also possible to apply both layers in a row without that intermediate drying is carried out beforehand. Depending on the speed the coating dries the layers at 60 up to 85 ° C.
  • the layer thickness of the underlayer preferably Is 15 to 20 ⁇ m.
  • the lower layer contains 50 to 75% by weight, preferably 55 up to 65% surface modified silica pigment, composed made from a mixture of flame-pyrolytic (fumed) and amorphous silica gels.
  • flame pyrolytic silica pigments produced are aerosil dispersions with a particle diameter of 0.1 to 0.3 ⁇ m, such as those manufactured by Degussa AG.
  • Silica gels for the purposes of the invention are amorphous precipitated silicas, as for example under the name Sylojet are offered by W. R. Grace.
  • the particle diameter these dispersions are 0.25 to 0.35 ⁇ m.
  • Both Pigments are modified separately by reaction with alkylsilanes at elevated temperature. This is preferably done Surface modification of the pigment particles at 60 to 80 ° C with methyltriethoxysilane.
  • the ratio of pyrogenic aerosil dispersions to silica gels can be 2: 1 to 1: 2 in the lower layer.
  • the proportion of plasticizers is 10 to 25% by weight in the lower layer.
  • water-insoluble Plasticizers are esters of aliphatic and aromatic Carboxylic acids or phosphoric acid esters such as dibutyl adipate, Adipic acid dihexyl ester, phthalic acid dibutyl ester, Phthalic acid dioctyl ester or trioctyl phosphate.
  • Ethylene glycol derivatives are suitable as water-soluble plasticizers such as tetraethylene glycol or higher molecular weight Polyethylene glycols.
  • the ratio of water soluble to water-insoluble plasticizers is generally 1: 1 to 2: 1.
  • the lower layer contains 15 to 30% by weight of polymeric, cationic color fixing agents. Preferably it contains a mixture of water-soluble and water-insoluble Dye fixative.
  • the water-insoluble, polymeric color fixative can both organically dissolved as well as used as an aqueous dispersion become'.
  • the ratio of water-soluble to water-insoluble Color fixative can be 2: 1 to 1: 2.
  • the top layer contains 40 to 70 wt .-%, preferably 50 to 60% surface-modified pyrogenic (flame-pyrolytically produced) Aluminum oxide pigment.
  • the particle size is 0.08 to 0.15 ⁇ m.
  • the particles are characterized by an amorphous Structure.
  • the modification is carried out analogously to that of the silica pigments Reaction with alkylsilanes, preferably with methyltriethoxysilane.
  • the pigment / silane ratio is 7/3 to 9/1.
  • the structure and amount of plasticizers and polymeric color fixatives corresponds to the composition of the lower layer.
  • the top layer contains 0.5 to 3.5% by weight of one or several dye stabilizers.
  • dye stabilizers such as suitable known compounds such as sterically hindered phenols, secondary aromatic amines or hindered alicyclic Amines (HALS compounds).
  • the top layer preferably contains water-insoluble dye stabilizers used in the water-insoluble Plasticizers are solved and in this form in the coating solution are introduced.
  • To improve substrate wetting and layer homogeneity can also contain surfactants in the layer, where especially non-ionic fluorine sites are very effective prove.
  • the present ink jet material is characterized by a high Drying speed, high water resistance and low Bleeding and fading of the ink dyes.
  • Example 1 The procedure of Example 1 is retained and continues 1.21 kg silica (Sylojet 703 C) with a medium particle size of 0.29 ⁇ m are 5 g phthalic anhydride and 0.74 kg given iso-propanol. After thorough mixing, 135 g of methyltriethoxysilane and heated to 70 ° C. with stirring. After a reaction time of 6 hours, the dispersion is cooled.
  • Example 1 The procedure of Example 1 is retained and continues 45.77 kg aluminum oxide dispersion (30%, medium particle size 0.12 ⁇ m), 14.5 liters of an aqueous solution are added, the 388g polyethylene oxide with a molecular weight of Contains 35000. 0.36 kg of phthalic anhydride are added to this mixture and 44.4 liters of isopropanol. After good Mixing is then followed by adding 4.1 kg of methyltriethoxysilane and the reaction solution is heated to boiling temperature.
