Abstract
A compound obtained through Michael addition reaction of an α-aminoacetophenone skeleton-containing compound (I) represented by the following general formula (1) and a reactive compound (II) having a function as a Michael acceptor is used as a photopolymerization initiator. In the general formula (1), Rrepresents an aliphatic group, Rto Reach independently represent an aliphatic group, etc., Rto Reach independently represent a hydrogen atom, Xrepresents a single bond or a C1-6 alkylene group, Xrepresents a carbonyl group, Yand Yrepresent a group represented by the following general formula (2). However, when Yand Yboth have a structure represented by the general formula (2), Xin at least one of them is —NH—. In the general formula (2), Xand Xeach independently represent a linear or branched alkylene group having 2 to 6 carbon atoms, Xrepresents a single bond, —O— or —NH—.
