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.

Laminated glass and preparation thereof

A surface treating method is described, which method comprising applying, between electrodes, a potential sufficient to cause corona discharge to occur in the presence of a gas which comprises molecules containing at least one atom selected from the group consisting of halogen atom, oxygen atom and nitrogen atom. The resultant corona discharge is applied to an object to be treated for the surface treatment of the object, said object being outside said electrodes. The excellent adhesive surface can be obtained when said object is separated from said electrodes at a distance in the range of 10 mm to 5 m.
