摘要

当暴露在紫外光下时，由于偶氮功能的分解，聚合偶氮磺酸盐失去其水溶性。这种效果可用于水性光印工艺。含有重复单元的偶氮磺酸盐和甲基丙烯酸甲酯的水溶性共聚物可以通过类似聚合物的反应[1,2]和直接共聚[3]交替合成。这两种聚合物在胶印工艺中作为光树脂的应用进行了评估。共聚制得的聚合物具有优异的光敏性、分辨力、成膜性能、在水中显影性能以及热稳定性和储湿稳定性。

Water-soluble photoresins based on polymeric azo compounds

Polymeric azosulfonates lose their water solubility when exposed to UV light due to decomposition of the azo function. This effect can be used in water-based photoprinting processes. Water-soluble copolymers of azosulfonate containing repeat units and methyl methacrylate have been alternatively synthesized by a polymer-analogous reaction [1,2] and by direct copolymerization [3]. Both polymer types have been evaluated for application as photoresins in offset printing processes. The polymer made by copolymerization is superior and shows excellent results for photosensitivity, resolution, film-forming properties, and development in water, as well as for thermal and moisture storage stability.
