Abstract
A method for anodizing and dyeing a metallic article including a decorated surface to be dyed, includes steps as follows: anodizing the metallic article to form an anodization layer on the decorated surface by an anodizing treatment, in which the anodization layer is porous with a number of holes; sealing the anodization layer of the metallic article anodized by a first sealing treatment in a first sealing solution, in which a contacting time of the anodization layer and the first sealing solution changes gradually along a predetermined direction, and thereby a depth of the holes of the anodization layer after sealing changes gradually along the predetermined direction; and coloring the metallic article sealed in a dyeing treatment.
