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
101 words
A method of making a paint film assembly, said method comprising the steps of: providing a paint film having a high gloss and DOI; providing a masking film comprising a urethane layer, and bonding the masking film to the paint film to form a masked paint film that is thermoformable and so that the masking film is readily removable from the paint film, wherein the urethane layer is operatively adapted so that after the masked paint film is thermoformed and the masking film is removed, the paint film retains its original high gloss and DOI, at least to a substantial degree.
Claim 2
Independent Claim
101 words
A method of making a paint film assembly, said method comprising the steps of: providing a paint film having a high gloss and DOI; providing a masking film comprising a urethane layer, and bonding the masking film to the paint film to form a masked paint film that is thermoformable and so that the masking film is readily removable from the paint film, wherein the urethane layer is operatively adapted so that after the masked paint film is thermoformed and the masking film is removed, the paint film retains its original high gloss and DOI, at least to a substantial degree.
Claim 3
Dependent Claim
26 words
The method as set forth in claim 1, further comprising the step of: separately forming the paint film and the masking film before said bonding step.
Claim 4
Dependent Claim
53 words
The method as set forth in claim 2, wherein said forming step forms a finished surface on the paint film and on the masking film, and said bonding step includes laminating together the finished surface of the paint film and the finished surface of the masking film to form the masked paint film.
Claim 5
Dependent Claim
131 words
The method as set forth in claim 2, wherein said separate forming step includes the steps of: forming the paint film onto a surface of one substrate having a high gloss and DOI so as to form a finish surface on the paint film having a high gloss and DOI; forming the urethane layer onto a surface of another substrate having a high gloss and DOI so as to form a finish surface on the urethane layer having a high gloss and DOI; removing the paint film from the one substrate and the urethane layer from the other substrate before said bonding step, wherein said bonding step includes laminating together the finish surface of the paint film and the finish surface of the urethane layer to form the masked paint film.
Claim 6
Dependent Claim
56 words
The method as set forth in claim 4, wherein the paint film being provided includes a clear coat layer and said step of forming the paint film includes forming the clear coat onto the surface of the one substrate so as to form a finish surface on the clear coat having a high gloss and DOI.
Claim 7
Dependent Claim
19 words
The method as set forth in claim 2, wherein the masking film being provided comprises a cast urethane layer.
Claim 8
Dependent Claim
33 words
The method as set forth in claim 2, wherein said method includes the steps of: thermoforming the masked paint film into a desired shape; and removing the masking film from the paint film.
Claim 9
Dependent Claim
41 words
The method as set forth in claim 2, wherein said method includes the steps of: thermoforming the masked paint film into a desired shape; bonding the masked paint film to a substrate; and removing the masking film from the paint film.
Claim 10
Dependent Claim
44 words
The method as set forth in claim 2, wherein said method includes the steps of: thermoforming the masked paint film into a desired shape; insert molding the masked paint film to a molded plastic part; and removing the masking film from the paint film.
Claim 11
Dependent Claim
22 words
The method as set forth in claim 2, wherein the paint film being provided includes a color coat layer containing metallic flakes.
Claim 12
Dependent Claim
61 words
The method as set forth in claim 1, wherein the paint film being provided includes a color coat layer laminated to a clear coat layer, and said step of bonding the masking film to the paint film includes bonding together the clear coat layer and the masking film so that the masking film is readily removable from the clear coat layer.
