Title: PAINT FILM ASSEMBLY WITH MASKING FILM
Abstract:
A paint film assembly (20) which includes a thermoformable paint film (22) having a high gloss and DOI and a thermoformable masking film (24) which is removably bonded to the paint film (22) so as to better protect the paint film (22), for example, during shipping and handling and during subsequent forming and processing (e.g., thermoforming and/or insert molding) of the paint film (22) onto an article or part, while substantially retaining the surface finish of the paint film (22), particularly the gloss and DOI. The masking film (24) comprises a urethane layer (28) that is laminated or otherwise bonded to the paint film (22) to form a masked paint film (32). The masking film (24) is thermoformable and/or moldable with the paint film (22) so as to form a thermoformable and/or moldable masked paint film (32). After the masked paint film (32) is thermoformed and/or molded, the masking film (24) is still readily removable from the paint film (22). The urethane layer (28) is operatively adapted so as to at least substantially retain the high gloss and DOI of the paint film (22) after the masked paint film (32) is thermoformed and/or molded and the masking film (24) is removed from the paint film (22).
