Abstract
A flexible lustrously metallized resinous article which comprises a molded article made of a thermoplastic polyurethane or a polyblend of a thermoplastic polyurethane and a thermoplastic synthetic resin, the molded article having been coated on the surface thereof with a flexible polyurethane paint as a base coat, a metal film applied by means of sputtering and a flexible polyurethane paint as top coat. The flexible lustrously metallized resinous article is manufactured by applying a flexible polyurethane paint as a base coat onto a molded article made of a thermoplastic polyurethane or a polyblend of a thermoplastic polyurethane and a thermoplastic synthetic resin, applying a metal film by means of sputtering onto the base coat after its curing, and thereafter applying a flexible polyurethane paint as a top coat onto the metal film. The resulting flexible lustrously metallized resinous article has a brilliant metallic luster and strong resistance to weathering action, abrasion, heat and warm water and when subjected to deformation the metallic film thereon will not crack. Thus, this article is useful as a protuberant ornaments, especially as protuberant parts of motor vehicles.
