Abstract
Paint film composites comprise sheet metal, a color layer, and an optional transparent protective layer. Methods of making and using the paint film composites, and shaped articles made thereby, are also disclosed.
Claims21
A method of making a paint film composite, the method comprising:
- contacting a curable composition with unpainted sheet metal and a major surface of a forming web to form a rolling bank of the curable composition being disposed at least partially between the unpainted sheet metal and the forming web, the curable composition comprising a colorant and a curable polymeric material precursor;
- passing at least a portion of each of the unpainted sheet metal, the forming web, and the curable composition through a nip while said at least a portion of the curable composition is sandwiched between the unpainted sheet metal and the forming web to provide a curable layer precursor;
- and
- at least partially curing the curable layer precursor to provide an opaque or translucent color layer comprising the colorant and a polymeric material.

A method of making a paint film composite, the method comprising:
- providing sheet metal having an opaque or translucent color layer disposed thereon, the color layer comprising a colorant and a first polymeric material;
- contacting a curable composition with the color layer and a forming web to form a rolling bank of the curable composition at least partially disposed between the color layer and the forming web, the curable composition comprising a curable polymeric material precursor;
- passing at least a portion of each of the sheet metal, the color layer, the forming web, and the curable composition through a nip while said at least a portion of the curable composition is sandwiched between the color layer and the forming web to provide a curable layer precursor;
- and
- at least partially curing the curable layer precursor to provide a transparent protective layer comprising a second polymeric material.

A method of making a paint film composite, the method comprising:
- providing a first forming web having an opaque or translucent color layer disposed thereon, the color layer comprising a colorant and a first polymeric material;
- contacting a curable composition with the color layer and a second forming web to form a rolling bank of the curable composition disposed between the color layer and the second forming web, the curable composition comprising a curable polymeric material precursor;
- passing at least a portion of each of the first and second forming webs, the color layer, and the curable composition through a nip while said at least a portion of the curable composition is sandwiched between the color layer and the releasable protective liner to provide a curable layer precursor;
- and
- at least partially curing the curable layer precursor to provide a transparent protective layer comprising a second polymeric material;
- separating the first forming web from the color layer;
- and
- permanently adhering the color layer to unpainted sheet metal with an adhesive.
