ABSTRACT:
A paint film assembly which includes a thermoformable paint film having a high gloss and DOI and a thermoformable masking film which is removably bonded to the paint film so as to better protect the paint film during shipping and handling, and during subsequent forming and processing (e.g., thermoforming and/or insert molding) of the paint film onto an article or part, while substantially retaining the surface finish of the paint film, particularly the gloss and DOI. The masking film comprises a urethane layer that is laminated or otherwise bonded to the paint film to form a masked paint film. The masking film is thermoformable and/or moldable with the paint film so as to form a thermoformable and/or moldable masked paint film. After the masked paint film is thermoformed and/or molded, the masking film is still readily removable from the paint film. The urethane layer is operatively adapted so as to at least substantially retain the high gloss and DOI of the paint film after the masked paint film is thermoformed and/or molded and the masking film is removed from the paint film.
