Abstract
Abstract Molded articles having contoured, decorative outer surfaces are disclosed. The articles comprise a molded polymer substrate and a decorative surfacing film adhered to one side of the substrate. The decorative surfacing film comprises a substantially molecularly unoriented cast polymer film formed from a weatherable polymer. The articles are particularly suited for use as automobile body panels and the like. Also disclosed is a method for making such articles, and a method for making sets of such articles for assembly into automobile bodies and the like.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
123 words
A decorative surfacing film for in-mold surfacing of a molded plastic article to impart a high quality surface appearance comparable to that of a high quality automotive paint finish, comprising a preformed molecularly unoriented liquid-cast weatherable fluoropolymer film, a bonding layer comprising a preformed film of a melt produced thermoplastic thermoformable olefin polymer different from said cast polymer film, and an adhesive layer adhering said bonding layer to said liquid-cast weatherable fluoropolymer film, said bonding layer having a thickness of at least 2 mils and sufficient to render the preformed decorative surfacing film shape sustaining when thermoformed, said cast polymer film having pigments therein for providing an appearance and color to the molded plastic article comparable to a high quality automotive paint finish.
Claim 2
Dependent Claim
