Description of the Related Art The anodizing method, which has been conventionally known as one of the methods for coloring the surface of a metal, involves immersing a product such as Ti whose surface has been degreased by alkali treatment in an electrolytic solution such as an aqueous phosphoric acid solution. By applying a direct current with the product as an anode and an Al plate as a cathode, an oxide film is formed on the surface of the product, and the voltage of the product is controlled to control the thickness of the oxide film. The color can be changed in various colors such as gold, brown, yellow, purple, green, pink, etc., and it has been traditionally used for decorations such as cufflinks, tie pins, earrings, eyeglass frames, construction materials such as curtain walls, audio exterior products, It is used as a surface coloring means for automobile exterior parts.

飾品の分野に幅広く適用できるものである。As described above, according to the surface coloring method of the present invention, even if a product such as an aluminum wheel for automobiles having a rough surface is coated with a resin coating, a metal coating is applied. Since the surface of the metal coating can be made smooth by using it as an undercoat, anodizing treatment enables glossy coloring, enhances the decorative effect, and improves the product value. Therefore, there is a beneficial effect that a beautiful glossy metal skin can be colored at low cost without polishing the surface of the product smoothly. Further, as the colored product, since the material and shape of the product are not limited, it can be widely applied to various fields of personal items and ornaments.
