Abstract:
1. An actinic energy ray-curable resin obtained by reacting an unsaturated monocarboxylic acid with a terminal epoxy group of an epoxy resin having an unsaturated group and a hydroxyl group in side chains and an epoxy group in a terminal and further reacting a polybasic acid anhydride with the hydroxyl group of said epoxy resin, wherein said epoxy resin is a product of the polyaddition reaction of a reaction product of a polybasic acid anhydride and a compound having at least one unsaturated double bond and one alcoholic hydroxyl group in a molecule, a compound having at least two carboxyl groups in a molecule, and a bifunctional epoxy compound, and said compound having at least two carboxyl groups in a molecule is at least one compound selected from the group consisting of 1,2-cyclohexene dicarboxylic acid, tetrahydrophthalic acid, hexahydrophthalic acid, hexahydroisophthalic acid, and hexahydroterephthalic acid and containing no aromatic ring.
