Abstract
A laminated glass is composed of glass plates, between which a thermosetting resin composed of a copolymer of ethylene-vinyl acetate, a hydrocarbon resin and an organic peroxide is inserted and cured to intergrate them. An organic resin film is inserted between layers of the thermosetting resin. The thermosetting resin contains dibenzylidene sorbitol and/or tribenzylidene sorbitol. The thermosetting resin contains one or more kinds of silane coupling agent selected from the group consisting of acryloxy group containing compound, methacryloxy group containing compound and aryl group containing compound, and an absorber for ultra violet ray are contained. Preparation of the thermosetting resin is carried out by previously mixing a part of the copolymer of ethylene-vinyl acetate with the hydrocarbon resin to obtain a mixture, mixing residual amount of the copolymer of ethylene-vinyl acetate into the mixture, and adding the organic peroxide to mix.
