(57) [Problem] To provide a raw material compound easily without the problem of skin irritation of the composition and discoloration and odor of the cured product, and excellent in storage stability of the composition and water resistance of the cured product. Provide an active energy ray-curable composition. An active energy ray-curable composition containing a compound having three or more cyclic imide groups represented by the following general formula (1). Embedded image [However, in the formula (1), R 1 and R 2 are each independently an alkyl group having 4 or less carbon atoms, or one of them is a hydrogen atom and the other is an alkyl group having 4 or less carbon atoms, Or a group forming a carbocyclic ring together, wherein R 3 is A linear or branched alkylene group having 1 to 6 carbon atoms, R 4 Is a residue obtained by removing a carboxyl group or an oxydicarbonyl group from a polybasic acid having three or more carboxyl groups or an acid anhydride thereof. m is an integer of 1 to 6, s and t Is an integer of 1 to 9, and s + t is 3 to 10. ] |
