Patent ID: 6861500

Claim:
A curable composition, characterized by comprising (A) an actinic energy ray-curable resin which is obtained by causing the reaction of (a) an oxetane compound containing at least two oxetane rings with (b) an unsaturated monocarboxylic acid and the subsequent reaction of (c) a polybasic acid anhydride with a primary hydroxyl group of the resultant modified oxetane resin (a′) and has at least one structure represented by the following general formula (1) and (B) a polymerization initiator. wherein R 1 represents a hydrogen atom or an alkyl group of 1 to 6 carbon atoms, R 2 , R 3 and R 4 independently represent a hydrogen atom, an alkyl group of 1 to 6 carbon atoms, an aryl group, an aralkyl group, a cyano group, a fluorine atom, or a furyl group, and X represents a polybasic acid anhydride residue.
