PROBLEM TO BE SOLVED: To provide a surface-treated metal plate excellent in abrasion resistance and press galling resistance having a surface dynamic friction coefficient of 0.10 or less and a static friction coefficient of 0.10 or more, and the surface-treated metal plate And a method for producing the same. SOLUTION: The upper layer of the chromate-coated plating metal plate is (1) aqueous resin, (2) colloidal silica, (3) water, (4) Modified fatty acid amide wax dispersion having a polar group, a molecular weight of 700 to 3000, and an acid value of 5 An aqueous organic composite paint composed of at least one lubricant selected from 40 modified polyolefin wax dispersions having a dry weight of 0.3 to 5.0 g. / M 2 and then baked to form an organic composite film. |
