Abstract
A sandwich glass comprising glass plates and an intermediate layer interposed therebetween is disclosed. The intermediate layer is formed by crosslinking or photocrosslinking a resin composition comprising an ethylenevinyl acetate copolymer and an organic peroxide or a photosensitizer under heating of the resin composition above the melting point of the copolymer.
