Description
Technical field
The present invention relates to a kind of printing ink, particularly relate to a kind of aqueous jet printing ink.
Background technology
In recent years, along with popularizing and the develop rapidly of advertising of computer, make the Application Areas of ink-jet print system and quantity increase sharply, the raising of the quality of resolving power and spray ink Printing has also reached surprising degree simultaneously.For the hard copy output of end, under the prerequisite that does not increase expense, further improve the quality of image simultaneously, improve the light fastness of ink jet print image, particularly its light fastness is vital when the image of the light tone that shows transition.
Aqueous jet printing ink is to be tinting material with the dyestuff.Dyestuff is soluble in solvent, that is to say that it is to dissolve fully in solvent, is vitreous state.Dyestuff is painted with molecularity or state of aggregation.Because the environmental facies of each molecule seemingly, so its absorption spectrum is sharp-pointed, demonstrates the color development of highly purified distinctness.And because no matter dyestuff is in solvent, or itself all becomes molecularity, so it demonstrates very high tinctorial yield.In addition, owing to do not have particle, so do not have scattered light, catoptrical generation.Therefore dye solution is not only well-illuminated, and keeps distinct form and aspect.In like manner, because the characteristic of dyestuff itself, make factor such as chemical reaction that its molecule is destroyed, the molecule number minimizing.This variation is directly reflected on the colorant density, so light permanency, weathering resistance are bad.And, owing to dissolve in the solvent, so also cause poor durability, bleeding and the migration of these solvents easily.
The feature of the tinting material of known other type is opposite with above-mentioned condition at present.Be insoluble in the solvent such as pigment, its molecular aggregates becomes the particle shape, and the state in the solvent of being dispersed in is with painted relevant.Therefore, at first be to be evenly dispersed in the solvent, if can not form stable dispersion, just can not make painted usefulness.If the formation particle even the molecule of same structure also can exist various differing moleculars owing to the influence of environment, broadens absorption spectrum, the distinctiveness of color development is relatively poor.The molecule of particle inside and color development are irrelevant, so compare with dyestuff, tinting strength is lower.And scattered light that particle causes and reflected light make its color development both opaque also not distinct.
At present,, be mainly concerned with in the printing ink, adopt pigment, reach the purpose of the light fastness that improves printing ink as tinting material at the solution that ink jet print image fades.For example: United States Patent (USP): US 5108504,5145519,5534051,5098478,5085698,5169438,5160372,5302197, European patent: EP 776952,712912, Chinese patent: CN1192459, all be to adopt pigment to replace dyestuff to prepare printing ink, or in dye ink, add the granules of pigments of water-based, by the inherent characteristic of granules of pigments own, it is the molecule of particle surface, because light reaction has caused destruction, but still also has new molecular layer in its underpart.Therefore tinting strength can not reduce, and since the vibration of molecular lattice it is had can make the effect of excited state demulcent, the good condition of pigment light fastness that Here it is.
But for granules of pigments, as if the look material as ink for inkjet recording, primary condition is to realize the dispersion stabilization of height.Secondly, also be significantly for the requirement of form and aspect sharpening, must with the color development level of dyestuff target.Therefore, be very important the pigment particles dispersive is thinner.But thin more the progenitor dispersive of pigment, then cohesive force is strong more, disperses difficult more.
Just because of above-mentioned reason, the distinct form and aspect of dyestuff and the cost of itself, than the cost of the high pigment of light fastness, price variance is bigger, and the cost of manufacture of image is lower.
The purpose of this invention is to provide the high aqueous jet printing ink of a kind of light fastness.

A stainless steel reaction that has electronic stirring holds still, according to the compound of mentioning among the present invention, add organic solvent, tensio-active agent, PH buffer reagent, sterilant, metal chelator, uv-absorbing agent, deionized water, dyestuff successively, stir, reaction is 2 hours under the room temperature, the filter element filtering of 3,1,0.45 ц m is used in discharging respectively, and the filtrate that obtains is aqueous ink-jet inks.
Uv-absorbing agent of the present invention, the mechanism of action and the example of print image light fastness that can improve ink-jet ink is as follows:
Following ultraviolet absorption peak bitmap is to use U-3000 SPECTROPHOTOMETER ultraviolet, visible spectrophotometer, to the example of above-mentioned two compounds, carries out the mensuration of ultraviolet absorption peak.
With first kind alkoxy benzene ketone compounds structural formula (2) is example, is abbreviated as UV1-(2).At first pure product are made into 0.005% the aqueous solution, in the uv-absorbing zone, do absorbing wavelength, peak position graphic representation, as shown in Figure 1.
As can be seen from Figure 1 several absorption peak positions of UV 1-(2) be respectively 317,285,226nm, the intensity of absorption peak is followed successively by 226nm＞286＞317, and the maximum peak district of its absorption, between 250-300nm.In the entire ultraviolet zone of 200-400nm, the absorption peak district of the compound of UV 1-(2) structure, between 275-325nm, entire curve has a peak valley at the 250nm place basically, absorbs at the 325nm place and weakens gradually, has not had absorption substantially at the 350nm place.Therefore from whole absorption curve as can be seen, the compound of UV 1-(2) structure leaves in ultraviolet region and does not have the clear area that absorbs, and to natural ultraviolet absorption just not exclusively, that is to say UV 1-(2) compound, absorption ultraviolet ray that can only part.When in water soluble dyestuffs printing ink, when adding UV 1-(2) compound, its main absorbing wavelength ultraviolet ray between 250-325nm, and between the 325-400nm, the ultraviolet ray to the harmful wavelength of dyestuff can only continue the dyestuff in the printing ink is damaged.Although after in printing ink, having added UV 1-(2) compound, can improve the light fastness of printing ink to a certain extent, there is the problem of two aspects.One: light fastness Δ % only improves 2-4% when not adding UV 1-(2) compound.Its two: the harmony of fading of CKMY four looks of image is very undesirable.The colour loss that shows as product look and black is the most serious.
In like manner, be example with the second class amine alkyl phenones compounds structural formula (2), be abbreviated as UV 2-(2).At first pure product are made into 0.005% the aqueous solution, in the uv-absorbing zone, do absorbing wavelength, peak position graphic representation.As shown in Figure 2:
As can be seen from Figure 2 several absorption peak positions of UV 2-(2) be respectively 366,249,210nm, the intensity of absorption peak is followed successively by 210nm＞366nm＞249nm, and the maximum peak district of its absorption, between 300-400nm.In the entire ultraviolet zone of 200-400nm, the absorption peak district of the compound of UV 2-(2) structure, between 325-400nm, absorption intensity is lower at the 225-325nm place basically, but entire curve has a crest at the 250nm place, forms a summit simultaneously at the 250nm place.From whole absorption curve as can be seen, the compound of UV 2-(2) structure to the ultraviolet absorption between the natural 225-325nm just not exclusively, that is to say UV 2-(2) compound, absorption ultraviolet ray that can only part.When in water soluble dyestuffs printing ink, when adding UV 2-(2) compound, its main absorbing wavelength is in the later ultraviolet ray of 325nm, and between the 225-325nm, the ultraviolet ray to the harmful wavelength of dyestuff can only continue the dyestuff in the ink is damaged.Although after in printing ink, adding UV 2-(2) compound, can improve the light fastness of printing ink to a certain extent, the same problem that exists UV 1-(2) compound to exist equally.
When the absorption peak position graphic representation of UV 1-(2) compound and UV 2-(2) compound is superimposed, as shown in Figure 3.
As shown in Figure 3, in the entire ultraviolet wavelength region may of 200-400nm, what UV 1-(2) compound mainly absorbed is the ultraviolet ray that wavelength is lower than the 325nm zone.And UV 2-(2) compound mainly absorbs is the ultraviolet ray that is higher than the 325nm wavelength, useful especially is, UV 1-(2) compound is a lowest point of absorption curve at the 250nm place, and UV 2-(2) compound just in time is the summit of a crest at the 250nm place, and both have formed a unusual good absorption complementation just in the 240-260nm scope.
With UV 1-(2) and UV 2-(2) with 1: 1 mixed after, do uv-absorbing peak position graphic representation.As shown in Figure 4.
Therefore, in entire ultraviolet line absorption zone, UV 1-(2) compound and UV 2-(2) compound overlapping effectively carried out hypersorption with the entire ultraviolet line.Effectively improved the light fastness of ink-jet ink.From Fig. 3 and Fig. 4 relatively, both mix the better effects if that back peak load shifting, balance absorb.
The present invention just is being based on above-mentioned mechanism, in ink-jet ink, has both added the compound of first kind structure, adds the compound of second class formation again, both in ultraviolet region, to ultraviolet absorption mutually complementation get.For ink jet print image, uviolizing is to image, and actual is that ink droplet has received ultraviolet ray.UV 1-(2) compound that contains in the ink droplet has absorbed 325nm with the ultraviolet ray in the lower area, UV 2-(2) compound that contains has absorbed the ultraviolet ray in the 325-400nm zone, be actually natural ultraviolet ray and absorb by UV 1-(2) compound and UV 2-(2) compound respectively, formed ultraviolet hypersorption in the entire ultraviolet zone.Be equivalent to water soluble dyestuffs herein by above-mentioned two kinds of compounds, effectively protected, slowed down the fading time of dyestuff, played the effect that improves the printing ink light fastness.
