<p>A flexible, weatherable decorative sheet material useful as a surfacing film for automobile parts is provided comprising a base layer (18) of extruded, pigmented, flexibilized polyalkyl methacrylate film and a substantially transparent clear outer layer (14) overlying a first surface of the base layer. The clear outer layer (14) comprises a film formed of a composition selected from the group consisting of urethane polymers, acrylic polymers, fluoropolymers, and alloys of a fluoropolymer and an acrylic polymer. The clear outer layer (14) may be extruded or cast in the form of a coating. The decorative sheet material further includes a color adjustment layer (16) between the base layer (18) and the clear outer layer (14), wherein the color adjustment layer comprises a layer of printing ink that optionally includes pigments, dyes, flakes, and mixtures thereof. The color adjustment layer has a transparency and tint necessary to alter the natural color appearance of the base layer to achieve a desired match to a predetermined automotive color standard. The base layer material may be used to bond the decorative sheet material to Low Pressure Molding Compounds and acrylonitrile-butadiene-styrene terpolymer molding substrates without additional backing layers. The decorative sheet material may include a thermoformable backing layer (22) adhered to a second surface of the base layer and designed to bond the decorative sheet material to thermoplastic molding resins. A method of making the above-described sheet material is also provided. <IMAGE></p> |
