Abstract: Transparent or translucent laminated safety glass having an at least two-layered structure, in which one outer layer is a relatively soft synthetic resin layer and the other outer layer is a hard substrate layer, characterized in that said relatively soft synthetic resin layer comprises: a surface layer of a reformed polyurethane type thermoplastic resin obtained by impregnating a polymerizable compound containing a polymerizable unsaturated group into a polyurethane type thermoplastic resin and polymerizing the compound; and an inner layer of a polyurethane type thermoplastic resin which is continuous or non-continuous with said surface layer.

Abstract: Laminated safety glass having an at least two-layered structure comprising an inorganic glass layer and a synthetic resin layer, and having an inorganic glass surface on one side and a synthetic resin surface on the other side, characterized in that the major portion of the synthetic resin layer comprises a polyurethane type thermoplastic resin, said polyurethane type thermoplastic resin being a resin obtained from a high molecular weight diol composed of a combination of from 40 to 70% by weight of a poly(1,6-hexylene carbonate)diol and from 30 to 60% by weight of a polyester diol, a chain extender, and a non-yellowing type diisocyanate compound, as essential starting materials.

Abstract: Transparent or translucent laminated safety glass having an at least two layered structure comprising a synthetic resin layer having an exposed surface and a hard substrate layer wherein the exposed surface of the synthetic resin layer has a cross-linked structure of cross-linkable groups introduced and cross-linked in said surface.
