Laminated safety glass

Claim 1

A liminated safety glass having an at least two layered structure of an inorganic glass layer and a synthetic resin layer, said laminated structure having an exterior glass surface on one side and a synthetic resin surface on the other side, with the major portion of the synthetic resin layer comprising a polyurethane type thermoplastic resin being obtained by the reaction of a high-molecular weight diol composed of a combination of from 40 to 70% by weight of a poly-(1,6-hexylene 1 carbonate)diol having a molecular weight of from about 800 to about 4000 and from 30 to 60% by weight of a polyester diol having a molecular weight of from about 1500 to about 3000, said polyester diol being a compound or mixture of compounds having dihydric alcohol and dibasic carboxylic acid groups, residual ring opened cyclic ester groups or combinations thereof, with a non-yellowing type of diisocyanate compound in the presence of from about 1.0 to about 10.0 equivalents, relative to one equivalent of the total amount of diol reactant of a chain extender, as essential ingredients, said diisocyanate compound being present in an amount of from about 0.90 to about 1.15 equivalents, per one equivalent of the total amount of said diol and chain extender, and said diisocyanate not having isocyanate groups directly bonded to an aromatic ring in the event the diisocyanate compound contains an aromatic ring, and said chain extender being a diol having a molecular weight of at most 400 and a diamine.
