<P>PROBLEM TO BE SOLVED: To provide a method for easily forming a pattern composed of a plurality of colors at a low cost on the surface of an aluminum member subjected to an anodization treatment. <P>SOLUTION: The method for forming a pattern composed of a plurality of colors includes: an oxidation coating forming process for forming an oxidation coating by applying an anodization treatment to an aluminum member; a coloring process for coloring the surface of the aluminum member, on which an oxidation coating is formed, by immersing the aluminum member in a dye for a predetermined time; a masking forming process for applying a masking treatment on the surface after the coloring treatment so that a predetermined pattern is formed; and a decoloring process for decoloring the colored color on the aluminum member subjected to the masking treatment. The method is characterized by forming a pattern composed of a plurality of colors on the surface of the aluminum member, by sequentially repeating the coloring process, the masking forming process, and the decoloring process after the decoloring process and finally peeling masking executed in a plurality of times. <P>COPYRIGHT: (C)2013,JPO&INPIT |
