ABSTRACT:
The present invention relates to a process for the preparation of plastic molded articles having a metal film and exhibiting a metallic luster, said process comprising (a) coating an ultraviolet-curing acrylic resin type undercoating paint on the surface of a plastic molded article and irradiating the molded article with ultraviolet rays to form a base coat layer, (b) forming a metal film layer of chromium or stainless steel on the base coat layer by a sputtering process, and (c) coating on the metal film layer a top coating paint comprising as main components an acryl polyol having an OH value of 10 to 200 and an acid value of 1 to 12 and a non-yellowing polyisocyanate and curing the top coating paint to form a top coat layer.
