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).
Ensemble de film de peinture (20) comprenant un film de peinture thermoformable (22) à brillant et DOI élevés et un film de masquage thermoformable (24) lié amovible au film de peinture (22) de manière à mieux protéger ce film de peinture, par exemple, en cours de transport et de manipulation et durant le formage et le traitement ultérieurs (par exemple, thermoformage et/ou moulage par insertion) du film de peinture (22) sur un article ou une pièce, tout en conservant sensiblement le fini de surface du film (22), en particulier le brillant et le DOI. Le film de masquage (24) comprend une couche d'uréthanne (28) laminée ou liée autrement au film de peinture (22), de manière à former un film de peinture masqué (32). Le film de masquage (24) est thermoformable et/ou moulable avec le film de peinture (22) de manière à former un film de peinture masqué thermoformable et/ou moulable (32). Une fois que le film de peinture masqué (32) est thermoformé et/ou moulé, le film de masquage (24) peut encore être facilement détaché du film de peinture (22). La couche d'uréthanne est adaptée efficacement de manière à maintenir, au moins sensiblement, le brillant et le DOI élevés du film de peinture (22) après que le film de peinture masqué (32) ait été thermoformé et/ou moulé, et que le film de masquage (24) ait été retiré du film de peinture (22).
