Abstract
A sandwich glass is disclosed containing a thermoset resin layer interposed between glass plates, wherein the thermoset resin layer, prior to thermosetting, contains an uncured resin composition containing: (a) an organic peroxide, (b) an ethylene-vinyl acetate copolymer, and (c) at least one compound selected from the group consisting of at least one acryloxy or methacryloxy group-containing compound and a hydrocarbon resin having a ratio of hydrogenation .gtoreq.91%; wherein the at least one acryloxy or methacryloxy group-containing compound is selected from the group consisting of 1-methyl-1,3-dimethacryloxypropane, 2,2-dimethyl-1,3-diacryloxypropane, 2,2-dimethyl-1,3-dimethacryloxypropane, 2-hydroxy-1-acryloxy-3-methacryloxypropane, 2-hydroxy-1,3-dimethacryloxypropane, 1-hydroxy-2-methyl-1,3-diacryloxypropane and 1-hydroxy-2-methyl-1,3-dimethacryloxypropane and the ethylene-vinyl acetate copolymer contains vinyl acetate in an amount of 10-50% by weight. The sandwich glass of the present invention results in an improved resistance to yellowing and less perspective distortion.
