Abstract:
1. A glass laminate comprising: (a) a glass layer, (b) a thermoplastic polymer interlayer laminated to the glass layer, (c) a polyester film layer laminated to the thermoplastic polymer interlayer, and (d) a clearcoat on the polyester film layer, wherein the clearcoat is a scratch-resistant composition obtained from reaction of (A) at least one hydroxyl-containing oligomer with at least one isocyanate-containing oligomer, wherein the at least one hydroxyl-containing oligomer has a molecular weight in the range of from about 300 to about 3,000 and is obtained by reacting multifunctional alcohol with cyclic monomeric anhydride to obtain an acid oligomer, and further reacting the acid oligomer with monofunctional epoxide, or (B) at least one anhydride-containing oligomer with at least one epoxide-containing compound.
