A color-bearing textile product which comprises fibers, a silver-gray metal layer formed on the surface of said fibers by sputtering, and a metal layer or metal compound layer of chromatic color formed on the surface of said metal layer by sputtering. The silver-gray metal layer is, for example, formed of titanium. The metal layer or metal compound layer of chromatic color is, for example, formed of gold, silver, copper, brass, or titanium nitride.

Color-bearing textile product

Metal-coated fibrous objects comprising a fibrous base material, such as raw fibers, yarns, fabrics and final textile products; a synthetic resin base coat applied thereto; and a layer of metal deposited on said base coat by sputtering to a thickness in the range from 50 to 10,000 .ANG.. The metal is selected from the group consisting of gold, silver, aluminum, tin zinc, nickel, copper, cobalt and chromium, or selected from the group consisting of Hastelloy X, Permalloy, stainless steels, titanium nitride and cobalt alloys. The sputtering is carried out in an atmosphere of an inert gas selected from argon, neon and xenon, under a pressure in the range from 3.times.10.sup.-4 to 9.times.10.sup.-2 Torr, and at an impressed voltage in the range from 200 to 1,000 volts.

Metal-coated fibrous objects

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 20-300.ANG. 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 20-300.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 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.

Colored resinous articles with concealed metallic luster

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.
