PROBLEM TO BE SOLVED: To provide a copolymer capable of replacing a diallyl phthalate resin, which can be subjected to various modifications because it possesses a hydroxyl group, is well compatible with various reactive diluents in the same way as the diallyl phthalate resin, and moreover shows excellent resistance to emulsification as an active energy ray-curable resin composition containing the reactive diluents.SOLUTION: Provided is a hydroxyl group-containing polymerizable copolymer obtained by subjecting a cyclic acid anhydride (A) and a glycidyl compound (B) having a polymerizable carbon-carbon double bond in a molecule to a polymerization reaction in the presence of triphenyl phosphine (C). |
