Colored resinous articles with concealed metallic luster

DETAILED DESCRIPTION OF THE INVENTION As a result of extensive researches made on various kinds of coating paints and the influence of the thickness of a metal film on the relationship between the metallic luster and the color tint of the resinous material, it has now been found that colored resinous articles with a concealed tone of metallic luster which gives them a deeply noble feeling and improved aesthetic value in appearance are obtained by a combination of specific coating paints with a specific metal film which is unbelievably thin from the normal sense for metallizing resinous articles.
The present invention has been accomplished on the basis of the above finding.
In accordance with one embodiment of the present invention, there is provided a colored resinous article with a concealed 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 as thin as 20-300 .
ANG.
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.
In accordance with another embodiment of the present invention, there is provided a process for the manufacture of a colored resinous article with lurking metallic luster, which comprises 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 20-300 .
ANG.
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 resinous molded articles used as substrate of the product of this invention are manufactured from various kinds of polymeric or polymerizable materials by injection molding, extrusion or the like means
