DECORATIVE SHEET MATERIAL WITH CHLORINATED POLYOLEFIN ADHESIVE LAYER

摘要

The flexible, weatherable decorative sheet material provided by the present invention comprises a thermoformable decorative paint film having an inner surface and a weatherable outer surface suitable for forming an exterior finish for a part, such as an automobile body part. The decorative sheet material includes an adhesive layer overlying the inner surface of the decorative paint film, wherein the adhesive layer comprises a chlorinated polypropylene component and a chlorinated polyolefin component. The chlorinated polypropylene component has a peel strength of at least about 0.8 lbs./in. at 100 DEG C and the chlorinated polyolefin component has a peel strength of at least about 5 lbs./in. at room temperature. The two chlorinated components have similar chlorine contents, such as between about 20 to about 40 weight percent chlorine. A method of constructing the decorative sheet material and a composite shaped part including the decorative sheet material are also provided.
