Abstract

A weatherable film for lamination to a non-weatherable substrate, including, for example a three-layer film structure including:at least one first surface layer of a weatherable polymer comprising (a) AES, ASA, SAN or mixtures thereof or (b) any of the polymers of (a) blended with PVC, CPE, aliphatic polyurethanes or saturated styrenic block copolymers; said layer having a 1 percent secant modulus of greater than about 150,000 psi;at least one second intermediate layer being a tie layer underlying the weatherable layer, said intermediate tie layer being adjacent to and adhered to the weatherable layer, said intermediate tie layer having a modulus of less than about 150,000 psi; said tie layer adherable to at least a third underlying layer; andat least one third layer underlying the tie layer, said third layer adjacent to and adhered to the tie layer said third layer having a modulus of less than about 150,000 psi.
