るなどの欠点があった。[Prior Art and Problems to be Solved by the Invention] Conventionally, coins used in game machines such as slot machines installed in game centers, pachinko parlors, etc. are made of copper.
Many products are made of nickel-plated brass, but these have a monotonous color, shape, and design, so they have little commercial value, and even if similar products are mixed in, they are almost impossible to tell apart, making it difficult to distinguish between them. The problem was that it was very difficult to remove. The same is true for stainless steel coins, which have recently become popular. Furthermore, these coins are heavy and place a burden on the entire peripheral equipment of the game machine, shortening the useful life of the entire peripheral equipment of the game machine. Furthermore, copper-nickel plated brass coins have the disadvantage that nickel adheres to the hands from the plating surface when used, resulting in a peculiar stain and odor.

用上使用不可能であった。[0003] The present inventors have also developed coins that have been colored by printing or applying UV ink or UV paint on the surface of copper-nickel plated brass coins, and then applying UV irradiation treatment directly to the surface of the brass. Attempts have been made to produce colored products by printing or applying ink or UV paint and irradiating them with ultraviolet rays, but the adhesion between the colored parts and the metal is weak, the water resistance of the colored parts is low, and the abrasion resistance is insufficient. This made it practically unusable.

る。[0017] The anodic oxide film can be colored by impregnating the metal surface with a dye for coloring the metal surface after the anodic oxide film is formed, thereby coloring the metal surface in various colors. At this time, the electrolyte is preferably about 15% sulfuric acid because the film is colorless and transparent and has excellent dyeability. The surface of the anodic oxide film of aluminum and aluminum alloys has a positive charge in an acid solution and has pores with a diameter of about 0.01 to 0.05 μm and a depth of about 5 to 25 μm. It can also be carried out by treating in an aqueous anionic synthetic dye solution at 50 to 60°C to adsorb dye molecules onto the surface of the oxide film. Further, the anodic oxide film can also be colored by printing with various printing inks instead of dyeing.

チングさらに前記陽極酸化の行程間各々で水洗を行う。[0020] In the step of applying anodizing treatment, it is preferable to first remove adhering fats and oils by degreasing treatment before performing anodizing treatment, and to perform etching to prevent uneven coloring and provide sharpness. Degreasing treatment includes organic solvent degreasing using trichlorethylene, perchlorethylene, benzyl, etc., alkaline degreasing using sodium carbonate aqueous solution, sodium hydroxide aqueous solution, emulsifier degreasing, preliminary degreasing, and finishing degreasing using sodium hydroxide aqueous solution. This can be carried out by a method such as an electrolytic degreasing method. Etching can also be carried out by a nozzle injection method, a beat method using a diffusion liquid, or an electrolytic corrosion method using an electrolytic machine, but alkaline etching is usually performed using an alkaline solution as the etching liquid. Examples of the alkaline solution include a sodium hydroxide aqueous solution and a potassium hydroxide aqueous solution. Water washing is performed between each of these degreasing treatment, alkaline etching, and anodic oxidation steps.
