Abstract
A tint film for application to a target surface, such as a headlight, includes a release liner, an adhesive layer, an at least partially transparent cast layer, and a tint layer. The tint layer is provided as an at least partially light-transparent layer, which may be printed upon the at least partially transparent layer using an ink-jet printing process. In addition, the adhesive layer is configured to have low-tack, so as to facilitate the ease in which the tint film is applied. In some cases, the at least partially transparent layer and the at least partially light-transparent tint layer may be formed together as a composite layer in a casting process.

A tint film comprising:
- an at least partially transparent layer having a first surface and a second surface, wherein said at least partially transparent layer comprises thermoplastic urethane (TPU) or cast polyvinylchloride (PVC);
- an adhesive layer in adhesive contact with the second surface of the at least partially transparent layer, wherein the adhesive layer has a tack of less than 400 gm/cm2, and wherein said adhesive layer includes at least one air channel having an end that extends to an edge of said adhesive layer, and wherein said air channel is separated from said at least partially transparent layer by said adhesive layer;
- a release liner in releasable adhesive contact with the adhesive layer on a surface of adhesive layer opposite the transparent layer;
