Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
92 words
A paint film assembly comprising: a thermoformable paint film having a high gloss and DOI; and a thermoformable masking film comprising a urethane layer bonded to said paint film and readily removable therefrom so as to form a thermoformable masked paint film, said masking film being readily removable from said paint film, and said urethane layer being operatively adapted so as to at least substantially retain the high gloss and DOI of said paint film after said masked paint film is thermoformed and said masking film is removed from said paint film.
Claim 2
Dependent Claim
92 words
A paint film assembly comprising: a thermoformable paint film having a high gloss and DOI; and a thermoformable masking film comprising a urethane layer bonded to said paint film and readily removable therefrom so as to form a thermoformable masked paint film, said masking film being readily removable from said paint film, and said urethane layer being operatively adapted so as to at least substantially retain the high gloss and DOI of said paint film after said masked paint film is thermoformed and said masking film is removed from said paint film.
Claim 3
Dependent Claim
20 words
The paint film assembly as set forth in claim 1, wherein said masking film comprises a cast waterborne urethane layer.
Claim 4
Dependent Claim
61 words
The paint film assembly as set forth in claim 1, wherein said masking film is operatively adapted to stretch substantially the same degree with said paint film during the thermoforming of said masked paint film, and said masking film exhibits a degree of recovery substantially similar to that of said paint film as said masked paint film cools after the thermoforming.
Claim 5
Dependent Claim
39 words
The paint film assembly as set forth in claim 1, wherein said masking film is at least as strong as said paint film during the thermoforming, and does not exhibit a substantial memory after cooling off from being heated.
Claim 6
Dependent Claim
49 words
The paint film assembly as set forth in claim 1, wherein said masking film is sufficiently bonded to said paint film to remain adhered thereto, without substantially separating, during the thermoforming of said masked paint film, and while still being readily removable from said paint film after the thermoforming.
Claim 7
Dependent Claim
44 words
The paint film assembly as set forth in claim 5, wherein said masking film is sufficiently bonded to said paint film to remain adhered thereto during the molding of said masked paint film and be readily removable from said paint film after the molding.
Claim 8
Dependent Claim
22 words
The paint film assembly as set forth in claim 1, wherein said paint film includes a color coat layer containing metallic flakes.
Claim 9
Dependent Claim
62 words
The paint film assembly as set forth in claim 1, wherein said paint film and said masking film are formed separately, said paint film exhibits a high gloss and DOI finish on one side, said masking film exhibits a high gloss finish on one side, and said paint film and masking film are laminated together with each one side facing the other.
Claim 10
Dependent Claim
25 words
The paint film assembly as set forth in claim 1, wherein said paint film assembly includes a substrate on which said paint film is bonded.
Claim 11
Dependent Claim
18 words
The paint film assembly as set forth in claim 9, wherein said substrate is a molded plastic article.
Claim 12
Dependent Claim
36 words
The paint film assembly as set forth in claim 1, wherein said paint film includes a color coat layer laminated to a clear coat layer, said clear coat layer being releasably bonded to said masking film.
