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.
