ABSTRACT:
A protective and decorative, stretchable, thermoplastic sheet material for bonding by thermoforming to automobile body panels and other articles comprises a polyester carrier film coated with an aqueous polyurethane paint composition. By coating the carrier film with a composition comprising an aqueous dispersion of a copolymer of ethylene with an ethylenically unsaturated carboxylic acid such as acrylic acid the adhesion of the paint to the carrier film is markedly improved. Especially significant is the improvement in adhesion to polyester carrier films of aqueous polyurethane metallic paints in which aluminum flakes are dispersed.
