More detail
Photochromic printing is also known as photochromic printing, early photochromic printing is photochromic dye, dye structure changes under the irradiation of ultraviolet light, showing different colors.For example, dye A is colorless. After exposure to ultraviolet light, the molecule rings into cyanine dye B, which is blue in color. When dye B is exposed to visible light, it changes back into colorless dye A.Now the microcapsule technology is used to coat the photodye in the capsule, and the general particle size is 1 ~ 10 micron. After being coated with the microcapsule, the photodye's light fastness is greatly improved.At present, photodye has developed into four basic colors: purple, blue, yellow and red. The initial structure of these four photodyes is closed-loop, that is, they have no color when printed on the fabric, but they can turn into purple, blue, yellow and red under ultraviolet light.The so-called photosensitive change color from one kind of color to another kind of color, is in the printing color paste in the light dye and the general color paint after mixing - from printing.For example, after the combination of dye-red and coating blue, the printing will appear blue on the surface of the fabric, and then turn bluish purple under ultraviolet light.

Extension and extension
Photovariable materials are widely used in the field of printing inks. According to their different USES, there are water-based inks, ink-based inks, plastic inks, interference inks and so on
The manufacturing method of this kind of ink, it is to change pigment of photochromic change to dissolve with solvent commonly, make microform pigment capsule, add binder according to different use in dissolving pigment.The better manufacturing method is to dissolve the photochromic pigments into coincidence monomers, grind the ultramicron particles of this kind of polymer into powder and use it as pigment. Compared with microcapsule inks, the light resistance of the inks made by this method is improved by 10 times.These powders can be added to water-based inks, oil-based inks and plastic inks, and all adhesives used as pigments.
Photochromic water-based screen printing ink
With its safe use, easy to operate and in the fiber products industry take the lead.The water-based ink is screen printed for 80-120 purposes, dried at 100 ° C for 1min (preferably overnight), and heated at 130 ° C for 3min for the bridge reaction, to obtain the product with excellent fiber density.The water-based ink features are as follows:
Anti - counterfeit Numbers printed with light - change ink
* Can rapidly develop color under sunlight, and restore colorless state in a short time after shading (different colors are different, yellow can be completed in 2~3min, cyan can be completed in an instant);
* Dispersion performance, can get uniform color printing;
* Good color rendering and friction firmness;
* This water-based ink belongs to liquid ink;
* Good storage stability, easy to operate.
