Abstract
The present invention provides a film-reinforced glass, which has excellent impact resistance, penetration resistance and durability and which can be easily prepared. The constitution of the glass consists of one glass plate and a film comprising an organic polymer which is superposed thereon through a transparent adhesive layer, wherein the transparent adhesive layer comprises a first transparent adhesive layer of polyvinyl butyral and a second transparent adhesive layer of ethylene-vinyl acetate copolymer; or wherein a hard coat layer consisting of a cured layer formed from a curable resin containing fine particles of silica is provided on the surface of the organic polymer film on the side in noncontact with the transparent adhesive layer.
