Description
Technical field
The present invention relates to a kind of manufacture method of schemochrome ink.
Background technology
Ink is people's one of necessary writing materials in all social activity, and usually, we are being called ink in order to writing words, the liquid-consumed material of describing picture, label symbol.According to historical document records, our ancestors can trace back to before the yellow emperor times in B.C. 26th century with black origin, and color inks also has the history in five, 6,000 years in China.
The color inks of selling in the market roughly can be divided into two large classes: the first kind is the dye ink of molecular level CL, this ink is composite solution completely, the probability of spanishing head is very little, be easy to after the air brushing by absorbed, beautiful in colour, and also cost is low, but this ink is non-watertight, and because dye molecule decomposes under uviolizing very soon, cause using under the outdoor ultraviolet ray just to have in one month obviously fading, so its purposes has significant limitation; The Equations of The Second Kind color inks selects the vivid pigment of color as tinting material, it is that solid pigment is ground to form very tiny particle, be dissolved in the special water solvent, be a kind of aaerosol solution or be half solution, color development is come on the surface that is attached to medium (such as copy paper or printer paper etc.) by the look material.Even the advantage of this ink is the China ink of also can not spreading and sinking on common paper because pigment itself is with regard to waterproof, also be not easy to be decomposed by UV-light, so it water-fast, photostabilization is also very strong.Therefore but the shortcoming of this ink is most paint ink all can make remained on surface look material, so, come even on the paper that glazed paper etc. has an even surface, can not depict the image of gloss.In addition, the manufacturing cost of paint ink is higher, so price is also expensive than dye ink, its price differential is up to more than two to four times.In sum, at present the problem that faces of color inks is pigment coloring, and the unstable and chemical pigment that have certain bio-toxicity of color makes the application of color inks be subject to great limitation.
Consider that people are to the various demands of color inks, need a kind of ink color that can make of exploitation beautiful bright-coloured, can make again ink color stable for a long time, therefore, a kind of novel light pigment color inks arises at the historic moment, Japan Seiko Epson Corporation increases light black color by the light India ink that adopts a kind of novel concept, thereby has improved the level expressive force in darker regions or black image and reduced granular sensation.This technology by adopting microcapsulary that each the small uniform pigment ink droplet in the ink is wrapped up by the microcapsule of transparent resin, has improved water-repellancy and the shelf time of color inks again.But because this technology employing is that pigment is as tinting material, so it is to be assessed that its stability still has, although it is inner that ink all is coated to the microcapsule of transparent resin, and by the resin film protection, this alleviation still can't fundamentally solve the unsettled problem of color; Simultaneously, this making method is loaded down with trivial details, and can't guarantee again coloured pigment uniform particles degree and all be coated in the microcapsule; In addition, what the use of coloured pigment was adopted all is the tinting material of chemical pigment, fails all the time to solve fully the bio-toxicity problem of color inks if be applied to biomaterial.
Therefore, a kind of making method is simple, and the color inks that color is beautiful, stability is high, bio-toxicity is low comes out.
