摘要： The invention relates to moldings, comprising a composite layered sheet or composite layered film, reverse-coated with a backing layer of plastic applied by an injection-molding, foaming, casting, or compression-molding method, where the composite layered sheet or composite layered film comprises (1) a substrate layer comprising, based on the total of the amounts of components A and B, and, if appropriate, C and/or D, which give 100% by weight in total, a from 1 to 99% by weight of an elastomeric graft copolymer as component A, b from 1 to 99% by weight of one or more hard copolymers containing units which derive from vinylaromatic monomers, as component B, c from 0 to 80% by weight of polycarbonates, as component C, and d from 0 to 50% by weight of fibrous or particulate fillers, or a mixture of these, as component D, and (3) a top layer composed of aliphatic thermoplastic polyurethane. The invention further relates to processes for producing these moldings, to their use in the motor-vehicle-exterior sector, and to motor-vehicle-exterior parts.
