Abstract:
A laminate, comprising;A) at least two substrate layers, and B) between said substrate layers an adhesive consisting essentially of a mixture of; i) an isocyanate terminated prepolymer with an isocyanate index greater than about 2, comprising the reaction product of an aliphatic polyester polyol or mixture of aliphatic polyester polyols and a polyisocyanate or mixture of polyisocyanates, and ii) a thermoplastic copolymer having a weight average molecular weight greater than 30,000 which is compatible with the isocyanate prepolymer, comprising the reaction product of vinyl chloride and at least one monomer capable of copolymerizing with vinyl chloride; where the thermoplastic copolymer contains at least 50% by weight vinyl chloride, at least 10% by weight of the monomer capable of copolymerizing with the vinyl chloride and is free of isocyanate reactive groups.
