Laminated glass

Abstract

Abstract PURPOSE:To provide laminated glass which has heat ray reflectivity and has high impact resistance by laminating an inorg. glass layer on one surface of an intermediate film, which is produced by sandwiching a heat ray reflective film between adhesive intermediate films, and laminating an org. glass layer on the other surface. CONSTITUTION:An inorg. glass layer is laminated on one surface of an intermediate film, which is produced by sandwiching a heat ray reflective film (e.g.; a substrate such as a polyester film which is coated thereon with metal such as Cu, Al or the like or metallic oxide such as Fe2O3, TiO2 or the like) between adhesive intermediate films (e.g.; plasticized polyvinyl butyral film, etc.), and an org. glass layer (e.g.; partially crosslinked polyurethane layer, etc.) is laminated on the other surface, whereby laminated glass is obtd. Heat ray reflectivity is provided by the heat ray reflective film, and the danger of damaging the human body by the scattering pieces of broken glass when the laminated glass is ruptured by impact is decreased by the lamination of the org. glass and the inorg. glass layer.
