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.
本发明提供了一种辐射固化组合物,从而可以轻松地将由 PVA 树脂和另一种粘合剂组成的成型体连接成复合材料,并且连接后的复合材料可以表现出更高的耐切割性。本发明的组合物包括:(A) 环脂族环氧化合物;(B) 具有至少一个羟基且平均分子量大于等于 500 的化合物;(C) 光酸发生器。通过由本发明辐射固化组合物的固化产物组成的粘合剂层 4 将粘合剂 3 层压在 PVA 成型体 2 的一个表面上,从而形成复合材料 1。
