Abstract

PURPOSE:To easily produce the title colored pattern-decorated metallic sheet consisting of a delicate color tone contrast by irradiating the surface of a metallic sheet colored by oxidation by laser light to locally reduce the thickness of the oxide film, and utilizing the difference between the interference colors due to the difference between the oxide film thicknesses. CONSTITUTION:A colored oxide film is previously formed in a fixed thickness on the surface of a metallic sheet, the film is irradiated by laser light to locally reduce the oxide film thickness, and a colored pattern is formed by the difference between the oxide film thicknesses. At this time, a pulse laser is preferably used for the irradiation of laser light, the irradiation is controlled by a computer, the coloration is changed while observing the result of coloring, and the density of irradiation energy and the pulse frequency are changed. By this method, a metallic sheet having a decorative pattern is easily produced.
