The present invention relates to a pattern coloring method for aluminum or aluminum alloy. BACKGROUND ART Electrolytic coloring has been well known as a pattern coloring method for aluminum or aluminum alloys (hereinafter referred to as aluminum materials). The present invention attempts to color an aluminum material with a pattern by forming a metal semi-mirror film by applying a metal vapor deposition method to the aluminum material. The objective is to obtain a vivid primary color colored film based on the action. The method of the present invention involves forming a transparent barrier-type anodic oxide film by anodizing an aluminum material in an electrolytic solution consisting of an aqueous solution of ammonium borate, boric acid, etc. Layer cut out stencils or masks on top,
Various metals are vapor-deposited from above to form a metal semi-mirror film corresponding to the pattern of the stencil or mask, resulting in a clear primary color colored pattern based on the interference effect of light. The first feature of the present invention is that an aluminum material is anodized in an electrolytic solution consisting of an aqueous solution of ammonium borate, boric acid, or the like. Through this anodizing treatment, a dense, thin (approximately 1 mm or less) transparent barrier type anodic oxide film is produced on the surface of the aluminum material, and this barrier type anodic oxide film can be obtained by the metal vapor deposition treatment described below. This is suitable for producing a light interference effect by the metal semi-mirror film. The second feature of the present invention is that a metal semi-mirror film is formed by metal vapor deposition on the barrier type anodic oxide film. This metal vapor deposition is performed by the apparatus shown in FIG. This vapor deposition apparatus is constructed by disposing a vapor deposition source 3 connected to a heater power source 2 in the upper part of a bell jar 1 which is kept in a vacuum state. Reference numeral 4 is a vacuum pump. Then, an aluminum material 5 after anodizing treatment and a stencil or mask 6 cut out in a pattern are placed on top of each other on the inner bottom of the bell gear 1, and a vapor deposition metal 7 (for example, aluminum, nickel, etc.) is placed on the vapor deposition source 3. The heater current is applied to the heater. Then, a semi-mirror film of evaporated and sublimated metal is formed from the pattern opening 6a of the stencil or mask 6 on the barrier type anodic oxide film on the surface of the aluminum material 5. Note that it is preferable to use a point source as the vapor deposition source 3 in order to make the transferred pattern clear. As shown in FIG. 2, a metal semi-mirror film 9 is formed on the barrier type anodic oxide film 8 of the aluminum material 5 treated as described above. Therefore, the light L 1 incident on the aluminum material 5 is reflected by the metal semi-mirror film 9 and the interface between the barrier type anodic oxide film 8 and the aluminum fabric 5a, and both reflected lights L 2 , L Due to the optical path difference 3 , a light interference effect occurs in which light in a specific wavelength range is strengthened, and a clear primary color colored pattern is obtained on the aluminum material 5. Note that, of course, various metals that can be vapor-deposited can be used as the vapor-deposited metal. Next, specific examples of the invention will be described. Example () Anodic oxidation treatment Aluminum material used: A1050 aluminum plate Electrolyte: 5 (W/V)% ammonium borate aqueous solution (25°C) Current conditions: 160V x 40min (DC) Counter electrode: Graphite Anode under the above conditions Oxidation is performed to form a thin, dense barrier-type anodic oxide film on the aluminum surface. () Metal evaporation treatment Evaporated metal: Various metals shown in Table-1 Evaporation source: Point source Vacuum level: 10 -4 Torr Stencil: Copper plate punched out by etching When metal evaporation treatment was performed under the above conditions, Table-1 shows the results. Colored patterns of various tones shown were obtained.

According to the present invention, the barrier type anodic oxide film formed on the surface of aluminum or aluminum alloy is masked and metal vapor deposited to form a colored pattern with the metal semi-mirror film, so that the light reflected by the metal semi-mirror film is An excellent effect is that a colored pattern having a clear primary color tone can be obtained based on the interference effect between the light and the reflected light after passing through the barrier type anodic oxide film.
