    摘要: 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.
