Dekoratives Element mit goldener Färbung und Verfahren zu dessen Herstellung

摘要

The golden decorative part of the present invention comprises a substrate and, formed thereon according to a dry plating process, an outermost coating, which coating comprises gold and titanium or iron together with inevitable ingredients in specific proportions. A Ti coating formed in an inert gas other than nitrogen, containing the inevitable ingredients may be disposed on the substrate, and a TiN coating may be disposed on the substrate or the Ti coating. The above golden decorative part having the outermost coating containing titanium does not cause allergic dermatitis, such as contact dermatitis, even if used in contact with the skin, and exhibits a uniform golden tone. Further, the above golden decorative part having the outermost coating containing iron is strikingly less likely to cause allergic dermatitis, such as contact dermatitis, even if used in contact with the skin, and exhibits a uniform golden tone. The golden decorative part having these advantages can be obtained by the process for producing a golden decorative part according to the present invention. The inevitable ingredients in this context are composed of at least one member selected from the group consisting of oxygen, carbon and nitrogen.
