鎓盐类阳离子光引发剂的研究进展

The Development of Onium Salt Cationic Photoinitiators

介绍了几种有代表性的鎓盐类阳离子光引发剂——芳基重氮盐、芳基鎓盐和二烷基苯甲酰硫盐的研究进展情况,探讨了各引发剂的光解机理和优缺点,并提出了增强鎓盐光敏性的方法和相关机理,介绍了有代表性的3类光敏剂以及近年来研制的一些新型光敏剂,概述了大分子鎓盐引发剂的研究情况,最后简要说明了鎓盐阳离子引发剂的发展趋势及应用。

Some representative onium salt photoinitiators were introduced, such as aryl diazonium salt, aryl onium salt and dialkyl phenacyl sulfonium salt photoinitiators. The photolysis mechanisms, advantages and disadvantaes of the photoinitiators were described in detail. The methods and corresponding mechanisms of increasing photosen- sitivity were proposed. Three types of representative photosensitizers and some new photosensitizers were described. Then the macromolecular onium salt initiator was summarized. Finally, the trend and application of onium salt initiator were described.
