Abstract
A article made by the method of applying a prepainted carrier film to an automobile body part in a vacuum thermoforming process. The article comprises a prepainted carrier film surface layer, an adhesive layer, and a rigid substrate layer. The prepainted carrier film has a top surface painted by a color coat formulation containing flakes and then coated with a layer of clear coat having a thickness of no less than 15 microns. The prepainted carrier film is heated and stretched in a vacuum thermoforming process and then assembled to a substrate for an automobile body part by adhesive means. The clear coat layer retains substantially the same gloss and color appearance of the stretched prepainted carrier film as prior to such stretch.
