Radiation-curable composition, composite and manufacturing method thereof

摘要

A radiation-curable composition, thereby a formed body composed of a PVAresin and another adherend can be easily joined to forma composite, and the composite after joined can exhibit higher cutting resistance, is provided. The composition of the present invention comprises (A) a cycloaliphatic epoxy compound, (B) a compound having at least one hydroxyl group and a number average molecular weight of 500 or higher, and (C) a photoacid generator. Composite 1 is formed by laminating adherend 3 on one surface of PVA-formed body 2 via adhesive layer 4 composed of a cured product of the radiation-curable composition of the present invention.
