Abstract

PURPOSE:To contrive to improve resistance to marring and chemical resistance by a constitution wherein the glass concerned consists of annealed glass plate, resin interlayer and water inpermeable film, which has specified thicknesses respectively. CONSTITUTION:The safety laminated glass concerned is constituted by bonding resin interlayer 2 on the indoor side surface of annealed glass plate 1 and further by bonding water inpermeable film 3, which is biaxially stretched so as to show no directional property, on the indoor side surface of the resin interlayer 2. As the resin interlayer 2, polyvinyl butyral is used. As the water impermeable film 3, polyethylene terephthalate is used. The thickness of the annealed glass plate is set to be 2.5 - 4.0 mm. The thickness of the interlayer is set to be 0.38 - 0.76 mm. The thickness of the water impermeable film is set to be 0.175 - 0.250 mm. Thus, safety laminated glass excellent in safety, see-through, durability and resistance to marring is obtained.
