Abstract

The invention relates to a phototonus resin composite unlikely to change colors and its application. The composite comprises a 0.1 to 50 wt percent water dispersible polymer, 0.1 to 50 wt percent water solubility bond polymer, 0.1 to 50 wt percent photocureable compound, 0.5 to 40 wt percent thermosetting compound, 0.1 to 10 wt percent diazonium resin or bichromate and proper additive. Compared with the prior art, the invention has the characteristic of unlikely to change colors in the producing art of rotary silk screen after being exposed and dried on the basis of keeping organic solvent resistance.

Description

technical field [0001] The invention relates to the technical field of organic polymer materials, in particular to a photosensitive resin composition which is not easy to change color and its application. Background technique [0002] At present, there are many types of photosensitive materials that can be developed with water, but they are all water-soluble resins containing hydrophilic groups, so images with good water resistance cannot be obtained. For good water developability, water-soluble compounds and surface active materials are added. agent, an emulsifiable compound with a hydrophilic group, and as a result, the hydrophilic compound remains after photocuring. Therefore, it is impossible to have sufficient water resistance, and when used in dyeing, the pigments and dyes in the dyeing paste penetrate into the image and react with the hydroxyl group of the water-soluble polymer in the image forming object to contaminate the image. The expected effect cannot be obtaine...
