Abstract

PURPOSE: To perform patterned coloring of color tones differing in corner parts and plane parts in the stage of subjecting Al type metallic products formed with an anodized film to patterned coloring of different color tones by interposing a specific treating stage between the fore and post coloring stage.
CONSTITUTION: An anodized film is formed on Al or Al alloy products and is subjected to primary coloring by electrolytic coloring. These are treated by a dip painting method and are stuck with paint, after which these are dried by heating to allow the solvent in the paint on the surfaces to evaporate away. Following to this, the electrolytically colored anodized film is electrolytically treated in an aq. soln. of acids or their salts with the Al metal to be treated as the anode to allow the metals and metallic salts deposited in the anodized film pores to elute, whereby the film is decolored. This is then subjected to a dyeing treatment or electrolytic coloring of the color tone differing from that by the primary coloring, where the patterned colored film having the different color tones by the primary coloring in the parts other than the corner parts and the secondary coloring in the corner parts is formed.
