Abstract:
The present invention is a laminated glass which is prepared by inserting a resin intermediate film between glass plates and adhering the glass plates to integrate them, having a bending deflection at 90° C. is 7.3 N/mm2 or higher, a weight per unit area is 7.5 kg/m2 or less, wherein the resin intermediate film contains a modified hydrogenated block copolymer [E] obtained by introducing an alkoxysilyl group into a hydrogenated block copolymer [D], storage elastic moduli in the dynamic viscoelastic properties of the resin intermediate film are 5×108 Pa or lower at a temperature of −20° C. and 2×107 Pa or higher at a temperature of 90° C., and the hydrogenated block copolymer [D] is obtained by hydrogenating 90% or more of carbon-carbon unsaturated bonds on a main chain and side chains and carbon-carbon unsaturated bonds on an aromatic ring in a specific block copolymer [C].
