Abstract

Abstract A colored resinous article having a lurking or underlying tone of metallic luster which comprises (a) a resinous molded article having been overlaid on the surface thereof successively with (b) a highly weather-resistant two-component polyurethane paint or UV-curable paint as a base coat, (c) a filmy layer of a metal of 20-300Å in thickness and (d) a highly weather-resistant and abrasion-resistant two-component polyurethane paint or UV-curable paint as a top coat, either of said (a) and said (b) having incorporated thereinto a material of a desired color tint. The colored resinous articles with a concealed tone of metallic luster are manufactured by applying onto the surface of (a) a resinous molded article (b) a highly weather-resistant two-component polyurethane paint or UV-curable paint as base coat, either of said (a) and said (b) having incorporated thereinto a material of a desired color tint, applying (c) a filmy layer of a metal of 20-300Å in thickness onto the base coat by means of dry plating, and then applying (d) a highly weather-resistant and abrasion-resistant two-component polyurethane paint or UV-curable paint as top coat onto said (c). The colored resinous article with a concealed tone of metallic luster possess a deeply noble feeling and strong resistance to weathering action and abrasion. Thus, these colored resinous articles are useful as outdoor ornaments, especially as ornamental parts of motor vehicles.
