ABSTRACT:
A flexible decorative sheet for use in surfacing an automobile body panel includes a first polyester carrier sheet having a high gloss surface, a clear coat of a weatherable optically-clear polymer containing fluorocarbon resin and an acrylic resin coated on the surface of the first carrier sheet, a tie coat on the clear coat, and a color coat containing a chlorinated polymer with dispersed pigments cast on the tie coat and dried. A pressure-sensitive adhesive layer is formed on a second polyester carrier sheet and then laminated to the exposed face of the color coat to form a pressure-sensitive, adhesive-backed composite paint coat between the outer carrier sheets which form protective removable backing sheets for the resulting laminate. The decorative sheet is applied to a substrate panel by pressure-sensitive adhesive bonding techniques, with the clear coat serving as a glossy, weatherable protective outer layer for the underlying color coat. The PVC-containing color coat enhances room temperature elongation of the finished film to enable application of the laminate to three-dimensionally contoured surfaces. The resulting paint finish has a defect-free, weatherable and durable outer surface with high gloss and high distinctness of image, meeting requirements for exterior automotive use.
