Abstract
Thermoformable laminate films with a decorative feature include a polymer carrier film, a paint layer and a protective clearcoat and the clearcoat and paint layer have a preconfiguration which causes desired decorative features following deformation of the laminate by a thermoforming process. The laminated film has a paint coat of a desired hue and the protective clearcoat has a variable thickness selected to produce a two tone appearance in a finished molded product. The process of manufacture includes the steps of painting a polymeric support or carrier film and laminating the painted carrier film by process steps which will control the finished appearance of the laminate when applied to an underlying relatively rigid substrate or body part.
