    • 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 of 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 releasable adhered to the carrier sheet. The adhesive layer is then laminated onto the base coat layer.
    • 用作漆膜或贴花的柔性,耐候性的装饰片材,其包含覆盖基本上透明的含氟聚合物透明涂层的着色氟聚合物底涂层,其中底涂层的含氟聚合物组合物具有比氟聚合物组合物更大的伸长率 涂层。 底涂层和透明涂层各自包含含氟聚合物组合物和丙烯酸类聚合物组合物的合金。 底涂层包含含氟聚合物共聚物组合物,透明涂层由含氟聚合物均聚物组合物组成。 在底涂层中使用的含氟聚合物的断裂伸长率为300%以上,透明涂层中使用的含氟聚合物组合物的断裂伸长率为50〜250%。 将透明涂层和底涂层浇铸到聚酯载体片上。 将粘合剂层浇铸到另一聚酯载体片上,使得粘合剂层可释放地粘附到载体片上。 然后将粘合剂层层压到底涂层上。

    • A flexible composite surfacing film for providing a substrate with desired surface characteristics is disclosed. The film comprises a flexible temporary carrier film and a flexible transparent outer polymer clear coat layer releasably bonded to the temporary carrier film, the flexible outer polymer layer comprising an extruded thermoplastic polymer having a M.sub.w /M.sub.n ratio of 4 or lower. A pigmented base coat layer is adhered to said outer clear coat layer and is visible therethrough, and a thermoformable backing layer is adhered to the pigmented base coat layer. The film is produced by extruding a molten transparent thermoplastic polymer and applying the polymer to a flexible temporary carrier thereby forming a continuous thin transparent film. A pigmented thermoplastic polymer in a volatile liquid vehicle is applied to the exposed surface of the transparent film while the film is bonded to the flexible temporary carrier, thus forming thereon a coating of the pigmented thermoplastic polymer overlying the transparent thermoplastic polymer film. The thus formed composite may then be heated while the transparent thermoplastic polymer film is bonded to the flexible temporary carrier to evaporate the volatile liquid vehicle and form a pigmented polymer layer. The heating step also molecularly relaxes the underlying film of transparent thermoplastic polymer to relieve any molecular orientation caused by the extrusion.
    • 公开了一种用于提供具有所需表面特性的基底的柔性复合表面膜。 该膜包括柔性临时载体膜和可释放地结合到临时载体膜的柔性透明外聚合物透明涂层,该柔性外聚合物层包含Mw / Mn比为4或更低的挤出热塑性聚合物。 着色底涂层粘合到所述外透明涂层上并且可见于其中,并且可热成型背衬层粘附到着色底涂层。 通过挤出熔融的透明热塑性聚合物并将聚合物施加到柔性临时载体上从而形成连续薄的透明膜来制造膜。 将挥发性液体载体中的着色热塑性聚合物施加到透明膜的暴露表面上,同时将膜粘合到柔性临时载体上,由此在其上形成覆盖透明热塑性聚合物膜的着色热塑性聚合物的涂层。 然后可以将如此形成的复合材料加热,同时将透明热塑性聚合物膜粘合到柔性临时载体上以蒸发挥发性液体载体并形成着色聚合物层。 加热步骤还分散地使下面的透明热塑性聚合物薄膜松弛,以减轻由挤出引起的任何分子取向。
