UV-ray absorbing sandwich glass comprising a specific thermosetting resin composition
First Claim
1. An ultraviolet ray-absorbing sandwich glass, comprising two glass plates and a cured resin layer interposed between the glass plates, said sandwich glass having been produced by interposing a thermosetting resin between two glass plates to form a monolithic structure, and thermosetting the resin layer interposed between the glass plates, said thermosetting resin being a homogeneous composition consisting essentially of:
- (1) an ethylene-vinyl acetate copolymer,(2) an organic peroxide,(3) a member selected from the group consisting of an acryloxy group-containing compound, methacryloxy group-containing compound and allyl group-containing compound,(4) a silane coupling agent, and(5) 5 parts by weight or less of 2,2'"'"'-dihydroxy-4-methoxybenzophenone, based on 100 parts by weight of the ethylene-vinyl acetate copolymer.

Abstract
A sandwich glass having high ultraviolet ray-absorbing ability is disclosed. This sandwich glass is produced by interposing a thermosetting resin between 2 glass plates to form a monolithic structure and thermosetting the resin layer, which thermosetting resin uses a benzophenone or benzotriazole series compound as an ultraviolet ray-absorbing agent in a thermosetting resin comprising an ethylene-vinyl acetate copolymer, an organic peroxide, an acryloxy group-, methacryloxy group- or allyl group-containing compound, a silane coupling agent and an ultraviolet ray-absorbing agent.
