PURPOSE: A photosensitive resin composition having improved adhesion to glass, comprising polyvinyl butyral resin, a hydroxyl group-containing (meth)acrylate, an epoxy group-containing acrylate crosslinking agent, and a photosensitizer. n CONSTITUTION: A photosensitive adhesive for bonding glass together, glass to plastic, and glass to metal, comprising (A) 5 wt.% or more of polyvinyl butyral resin, preferably having a butyralization degree of 60W70% and a polymerization degree of 200W1,000, (B) a hydroxyl group-containing (meth)acrylate, e.g. 2- hydroxyethyl methacrylate, (C) a crosslinking agent, e.g. glycidyl methacrylate, having at least one epoxy group and one (meth)acrylate unsaturated bond in the same molecule, and (D) 0.5W5 wt.% of a photosensitizer, e.g. benzoin ethyl ether. n COPYRIGHT: (C)1979,JPO&Japio |
