Definitions
- the present invention relates to the field of liquid pigment inks, in particular those intended for ink jet printing.
- Such inks are made up of a black or colored pigment, which is suspended in a vehicle.
- This vehicle generally comprises at least one compound which can be oxidized or crosslinkable by UV, that is to say capable of polymerizing by solidifying by exposure to air or to ultraviolet radiation, and a volatile, organic or aqueous solvent.
- the role of the solvent is to give the ink composition the fluidity or viscosity necessary to be easily “ejected” from the nozzle of the print head, and also to prevent, during stops, that the ink does not take up en masse by clogging the canals.
- the solvent After printing, that is to say the deposit of ink on the surface of a support, the solvent must be removed by evaporation and / or penetration into said support if the latter is more or less porous. This drying must be rapid, which implies either the presence of a small amount of solvent in the ink composition, or a high volatility of the latter.
- Japanese patent JP07041712 describes an ink preparation of this type, prepared by dispersion in water of a UV crosslinkable compound, such as a (meth) acrylic monomer.
- the object of the present invention is therefore to overcome all of these drawbacks by proposing an ink having the necessary fluidity at the time of ejecting the print head and not likely to clog the channels of the ejection nozzle during interruptions or prolonged stops.
- the composition of this ink must not contain any solvent to be evaporated (neither volatile organic nor aqueous), and be compatible with current technologies of inkjet printing, for operation at room temperature, especially in cases where it is neither intended nor possible to heat the print head itself.
- the ink must also be stable over time, mainly during storage, the dispersion remaining perfectly homogeneous, without any sedimentation of the pigment particles, or polymerization (solidification of the ink).
- the ink after depositing on the support to be printed and drying, must have an excellent mechanical resistance, in particular to scratches as well as a good resistance to water.
- liquid pigment ink which comprises a pigment in suspension in a vehicle based on a first monomeric or (meth) acrylic oligomer compound crosslinkable by UV, in the presence of a quantity of photoinitiator corresponding to this first compound and which is characterized in that it does not contain an aqueous or volatile organic solvent, and in that the vehicle contains at least one second monomer or oligomer compound, crosslinkable by UV, without additional addition of photoinitiator, the second compound being compatible with said first compound, and of viscosity less than or equal to that of the latter, and being added in proportions such that the final viscosity of the ink is less than about 20 mPa.s at a temperature between 15 and 35 ° C approximately.
- the polymerization of the monomers or oligomers constituting the vehicle does not take place in the narrow channels of the nozzle, the crosslinking occurs only after printing, when they are exposed to ultraviolet radiation.
- the first compound is advantageously a monomer or oligomer very reactive to UV, such as the compounds comprising for example from one to six acrylic groups.
- the second compound serves as a sort of diluent for the first compound, so as to lower if necessary the overall viscosity of the vehicle carrying the pigment, for good "ejection" of the ink from the nozzle of the print head and is also itself reactive to UV, like said first monomeric or oligomeric compound.
- the compounds which may fall into the category of said second compound must be compounds compatible with the first compound, in particular from the point of view of miscibility.
- the second compound is also a (meth) acrylic, or vinyl, preferably mono- or di-functional, monomer or oligomer or a mixture of several of these monomers or oligomers.
- the ink according to the present invention comprises approximately 9 to 20% by weight of the first monomeric or (meth) acrylic oligomer compound, from 0.2 to 4% of photoinitiator, up to 6% by weight of pigment and from 70 to 85% by weight of the second compound.
- the amount of photoinitiator can advantageously be less than 3 or 4% by weight, or even less than 1% by weight in the final ink composition, but always greater than or equal to approximately 0.2% to ensure minimum reactivity. If the viscosity of the final ink is less than 20 mPa.s, or even 15 mP.s, or less, the said first and second monomeric or oligomeric compounds can be identical (i.e. the vehicle n 'consists of only one and the same monomer or oligomer), and the amount of photoinitiator does not exceed 1% by weight of the final ink.
- the pigment consists of finely divided particles (of the order of 20 to 500 nm) of organic pigments of different colors, possibly supplemented with titanium dioxide and / or carbon black.
- These pigment particles are, in the present invention, preferably covered with a coating material which is a polymer, which makes it possible to obtain particles which are practically unitary, that is to say non-agglomerated.
- This polymer is advantageously soluble, at least partially, in the second compound so as to "unfold" it around the grain of pigment, this in order to allow better maintenance in suspension in the vehicle.
- the coating material may for example be based on a cellulosic (for example ethylcellulose), aldehyde, (meth) acrylic, vinyl (vinyl chloride, vinyl acetate), polypropylene or polyethylene polymer.
- the pigment ink composition according to the present invention may also contain a slip agent and / or a spreading agent.
- This additive can be present in an amount less than or equal to 3%, preferably 1% by weight.
- a slip agent gives the ink improved scratch resistance performance, it also improves the spreading of the ink.
- a spreading agent mainly contributes to reducing the surface tension.
- slip agents are silicone acrylates, polyether / silicone copolymers or also polysiloxane / polyether copolymers. These latter slip agents also allow the superposition of several layers of ink.
- the process for preparing the ink composition according to the present invention comprises a first step of dispersing the pigment particles in said second compound in a "ball mill” with fine beads, in a way “sorting out” or unfolding the polymer of coating the pigment particles. Under the effect of shear forces, this step is generally slightly exothermic, the coating polymer becomes more malleable after a few minutes and is partially dissolved in said second compound. Cooling is usually necessary before starting the second step, which consists in adding to this dispersion the mixture of the first compound with the corresponding amount of photoinitiator, a mixture carried out beforehand and carefully stored away from light. Finally, the slip and / or spreading agent is optionally incorporated into the ink.
- Example 1 with volatile organic solvent
- the pigment, coated with a type N ethylcellulose polymer, is first suspended in a solution of glycol ethers in a 15% pigment / 85% ratio glycol ethers (dispersion A).
- This ink composition has good machinability on the MIT piezoelectric printhead.
- the machinability test consists of operating the print head under impulse for 15 minutes, stopping it for 10 minutes, then restarting it for 5 minutes, stopping it for 15 minutes and finally restarting it for 5 minutes.
- the ink obtained has a good gloss, but with a tendency to yellowing. Its reactivity to UV is weak, its adhesion poor, and its mechanical resistance is weak. This composition also has the disadvantage of containing 70 to 85% of volatile organic solvents, which must then be evaporated.
- Example 2 Compared to Example 1, the solvents based on glycol ethers are replaced by monomers or oligomers reactive to UV.
- the same pigment is "ground” (mixed) with various monomers or oligomers (in the ratio 15% of pigment, 85% of monomer or oligomer): urethane monoacrylate, hexane diacrylate 1,6-diol, l 'tetrahydrofurfuryl acrylate, a mixture of octyl and decyl acrylates (ODA).
- various monomers or oligomers in the ratio 15% of pigment, 85% of monomer or oligomer: urethane monoacrylate, hexane diacrylate 1,6-diol, l 'tetrahydrofurfuryl acrylate, a mixture of octyl and decyl acrylates (ODA).
- the dispersion in the ODA is chosen for its very low viscosity (2 to 3 mPa.s) which makes it possible to have a low viscosity of the final ink while retaining a high proportion of pigment.
- dispersion B The dispersion 15% of pigment in 85% of ODA constitutes dispersion B:
- the chlorinated polyester is here tested to improve the adhesion, in particular for its good compatibility with vinyl supports.
- the other two types of "first compound" are chosen for their good viscosity / reactivity compromise.
- ODA is a very good reactive diluent, which is perfectly suited as a second compound.
- ODA is a very good reactive diluent, which is perfectly suited as a second compound.
- the best adhesion / scratchability compromise is obtained with the ink of composition d).
- Example 3 (comparative): with volatile organic solvent
- the coating of the pigment is here a polymer based on vinyl aceto-chloride, hard polymer, which has a good affinity with the supports in plastic materials.
- This pigment is dispersed in glycol acetates (in the respective weight ratio 15/85) to form dispersion C.
- Example 4 The major drawback of this composition is that it contains solvents (here around 22% by weight).
- Example 4 The major drawback of this composition is that it contains solvents (here around 22% by weight).
- Example 3 The same pigment as that of Example 3 is used and is dispersed in ODA.
- Pigment 2.8 to 4.2% + coating: 2.8 to 4.2% (vinyl resin)
- first compound urethane monoacrylate: 9.5 to 14.1% photoinitiator: 0.5 to 0, 7% slip agent: 0.2 to 0.3%
- second compound ODA 84.1 to 76.4%
- Example 5 Taken from example 4, a standard ink according to the invention is prepared, with a pigment identical to that of example 3, dispersed in ODA.
- This standard ink has the following composition:
- This ink has a final viscosity of 9.35 mPa.s at 25 ° C.
- inks according to the invention are prepared by modifying, with respect to the above standard ink serving as a reference, the nature of the first compound, monomer or oligomer.
- first compounds have been tested:
- the viscosity of these inks is between 9.5 and 12 mPa.s (at 25 ° C). The tests carried out show that these five inks have excellent mechanical resistance (scratchability) as well as good resistance to water (more particularly ink 5d containing the acrylated oligomer.
- the inks 5c, 5d and 5e also exhibit excellent resistance to chemical agents such as fuel oil, gasoline and other solvents (alcohols, ketones, esters).
- the solvent-free pigment ink according to the present invention can be used for printing by ink jet with piezoelectric or thermal excitation, on any porous or non-porous support, such as textiles, metals, ceramics, glass, wood, paper and plastic supports (eg PVC). TABLE 1
