Abstract:
1. A two component laminating adhesive comprising Component A comprising at least one polyisocyanate-functionalized polyurethane prepolymer, and Component B comprising at least one of (a) a polyhydroxyl-functionalized polyester derived by reacting a polyhydroxyl-functionalized transesterification product and at least one polybasic acid or alkyl ester or anhydride thereof and (b) a polyhydroxyl-functionalized urethane prepolymer derived from said polyhydroxyl-functionalized transesterification product, wherein said polyhydroxyl-functionalized transesterification product is obtained by a process comprising transesterifying at least one polyalcohol containing at least three hydroxyl groups per molecule with at least one fatty acid triglyceride, and said polyhydroxyl-functionalized transesterification product has a viscosity of from about 100 to about 500 centipoise when measured at 25° C.
