Abstract
A hydrophilic coating having excellent hydrophilicity, which can prevent offensive odor generation, and which has a good antibacterial performance and formability, is formed on an aluminum-containing metal material by coating an aqueous hydrophilization treating liquid containing (A) a glycidyl group-containing, water-soluble organic compound; (B) a water-soluble polymeric or polymerizable compound having a tert-amino group and at least one hydrophilic functional group selected from sulfonic, phosphonic, carboxyl, polyalkyleneglycol, hydroxyl and amide groups; and (C) an antibacterial agent not decomposing at 100.degree. C. or lower, on an aluminum-containing metal material; and heat-drying the coated liquid.
