<P>PROBLEM TO BE SOLVED: To provide an epoxy group-containing polyisocyanate derivative having excellent standing stability, and a photocurable resin composition using the polyisocyanate derivative having excellent standing stability, adhesion, and heat resistance. <P>SOLUTION: The polyisocyanate derivative has urethane bonds formed from a polyisocyanate group in a polyisocyanate compound (a1) and each of a hydroxyl group of an epoxy resin (a2) and a hydroxyl group of a hydroxyl group-containing (meth)acrylate (a3). The photocurable resin composition uses the polyisocyanate derivative. <P>COPYRIGHT: (C)2004,JPO |
