Substituted dibenzatketones useful as watersoluble photoinitiators have the formula:
wherein R' and R2 are 4, alkyl or, taken together, an aliphatic ring, n = O or an integer and R3 and R4 either are both water-solubilising groups (a) -X(CH2)mN+R53, (b) -X(CH2)mCOO-M or (c) -X(CH2)mSO-3M or one is such a group and the other is (d) a group -NR52, X is -CH2- -O- or -S-, R5 is an alkyl group, M is H+ or a metal cation and m = O. Such a photoinitiator compound is associated with a polymerisable compound in an aqueous photopolymerisable composition.
可用作水溶性光引发剂的取代二苯酮具有以下式子:
其中 R' 和 R2 是 4、烷基或合起来是脂肪环,n = O 或整数,R3 和 R4 要么都是水溶性基团 (a) -X(CH2)mN+R53、(b) -X(CH2)mCOO-M或 (c) -X(CH2)mSO-3M,或者一个是这样的基团,另一个是 (d) 基团-NR52,X 是-CH2- -O-或-S-,R5 是烷基,M 是 H+或金属阳离子,m = O。这样的光引发剂化合物与可聚合化合物结合在水性可光聚合组合物中。
