| 摘要 |
The present invention improves curability and reduces post-curing migration in a photopolymerization initiator. As a photopolymerization initiator, the present invention uses a compound obtained as a result of a Michael addition reaction between an α-aminoacetophenone skeleton-containing compound (I) represented by general formula (1), and a reactive compound (II) which functions as a Michael acceptor. (In formula (1), R1 represents an aliphatic group or the like, R2-R3 each independently represent an aliphatic group or the like, R4-R7 each independently represent a hydrogen atom or the like, X1 represents a single bond or a C1-6 alkylene group, X2 represents a carbonyl group or the like, and Y1 and Y2 represent a group represented by general formula (2) or the like. Meanwhile, when Y1 and Y2 both have a structure represented by general formula (2), the X5 in one or both is -NH-.) (In general formula (2), X3 and X4 each independently represent a C2-6 straight-chain or branched alkylene group or the like, and X5 represents a single bond, -O-, or -NH-.) |
