<p>A flexible, weatherable, decorative sheet material useful as a paint film or decal comprising a pigmented fluoropolymer base coat layer overlying a substantially transparent fluoropolymer clear coat layer wherein the fluoropolymer composition of the base coat layer has a greater elongation than the fluoropolymer composition of the clear coat layer. The base coat and clear coat layer each comprise an alloy of a fluoropolymer composition and an acrylic polymer composition. The base coat layer comprises a fluoropolymer copolymer composition and the clear coat layer comprises a fluoropolymer homopolymer composition. The fluoropolymer used in the base coat layer has a produced elongation at break of 300 % or greater and the fluoropolymer composition used in the clear coat layer has a produced elongation at break of 50 % to 250 %. The clear coat and base coat layers are cast onto a polyester carrier sheet. An adhesive layer is cast onto another polyester carrier sheet such that the adhesive layer is releasably adhered to the carrier sheet. The adhesive layer is then laminated onto the base coat layer.</p> |
