Colored copper plating method, colored copper plating solution and colored copper plating film

摘要

PROBLEM TO BE SOLVED: To provide a coloring copper plating method and a coloring copper plating solution with which a coloring copper plating film having a color tone other than a copper color can be obtained, and the color plating film which has the color tone other than the copper color, according to the present invention.SOLUTION: A coloring copper plating method is a copper plating method for obtaining a colored electroless copper plating film for achievement of the program to be solved, and the method comprises: dipping a body to be plated in an electroless copper plating solution and thus forming an electroless copper plating film on a surface of the body to be plated through electroless plating processing; and then carrying on the dipping even after a precipitation reaction of copper ends so as to change the color tone of the electroless copper plating film. The colored copper plating film is a copper plating film which is the colored electroless copper plating film, and has silver or one of hues classified by YR(yellowish red), Y(yellow), GY(yellowish green), G(green), BY(bluish green), B(blue), and RP(reddish purple) represented by the Munsell color system.SELECTED DRAWING: None
