Abstract
PURPOSE: To obtain a colored film with excellent adhesiveness and reproducibility by adding a fatty acid or either one of aromatic mono-or poly-carboxylic acid having a predetermined number of carbons to the coloring anodic oxidation treatment bath containing an alkane sulfonic acid and a metal salt thereof.
CONSTITUTION: An electrolytic bath containing an alkane sulfonic acid shown by a general formula R1-SO3H or a hydroxyl group containing alkane sulfonic acid shown by a general formula HO-R2-SO3H and either one of metal salts of two kinds of the above described acids is prepared and, further, 1W12C fatty acid or either one of 6W12C aromatic mono-or poly-carboxylic acid is added thereto. In the resulting electrolytic bath, pretreated Al or Al alloy is immersed to carry out electrolysis.
