Abstract
Abstract Elastic metallized decorative moldings are disclosed composed of a modified polyurethane resin as a substrate coated on the surface thereof with a metallized layer, the polyurethane resin comprising 50-95 parts by weight of a thermoplastic polyurethane resin incorporated with 5-50 parts by weight of an acrylonitrile-butadiene-styrene resin comprised of at least 75% by weight of an acrylonitrile-styrene component and not more than 25% by weight of a butadiene component. Such elastic metallized decorative moldings are useful as impact-absorbing materials with beautiful appearance for various structures, especially as bumper moldings for motor vehicles.
