Abstract
Abstract Plastic moldings, preferably comprising a polypropylene molding composition comprising from 95 to 50 parts by weight of isotactic polypropylene or a copolymer of propylene containing up to 10% by weight of ethylene, from 5 to 50 parts by weight of rubber-like, polypropylene-compatible copolymers and from 0 to 50 parts by weight of reinforcing fillers in the underlayer, suitably colored and provided with a single-layer paint coat, are highly suitable for external applications on automobiles.
