As a photopolymerization initiator, it reduces migration after curing and improves curability. A compound obtained by a Michael addition reaction of a compound (I) having an α-aminoacetophenone skeleton represented by the following general formula (1) and a reactive compound (II) having a function as a Michael acceptor was used as the photosensitive compound. polymerization initiator. (In general formula (1), R 1 represents an aliphatic group, etc., R 2 to R 3 each independently represent an aliphatic group, etc., R 4 to R 7 each independently represent a hydrogen atom, etc., X 1 represents a single bond Or a C1-6 alkylene group, X 2 represents a carbonyl group, etc., Y 1 and Y 2 represent a group represented by the following general formula (2), etc. Wherein, Y 1 and Y 2 have the group represented by general formula (2) at the same time structure, at least one of X 5 is -NH-.) (In the general formula (2), X 3 and X 4 each independently represent a linear or branched alkylene group having 2 to 6 carbon atoms etc., X 5 represents a single bond, -O- or -NH-). |
