<p>A method of producing corrosion resistant, lightfast green coating on aluminum or an aluminum alloy wherein an initial anodic coating is formed on the aluminum or aluminum alloy. The anodized item is then placed in an electrolyte containing silver or silver and copper ions, and the metal ions or compounds thereof are electrolytically desposited into the pores of the anodic film which imparts a yellow color resembling gold to the anodic film. The colored anodic film is then dyed with a light fast blue organic dye. The resulting green colored coating is lightfast and corrosion resistant.</p> |
