| titleOfInvention | Composition for chemical conversion treatment and method for producing member comprising chemical conversion film formed by the composition |
| abstract | A water-soluble trivalent chromium-containing substance of 0.05 mol / L or more in terms of chromium with respect to the total composition as a chemical conversion treatment liquid capable of forming a chemical conversion film that is excellent in corrosion resistance and appearance and has reduced elution amount of hexavalent chromium A water-soluble acidic composition comprising one or more water-soluble hydroxycarboxylic acid substances selected from the group consisting of hydroxycarboxylic acids, and ions, salts and coordination compounds thereof, There is provided a chemical conversion treatment liquid in which the ratio of the molar concentration of hydroxycarboxylic acid in terms of hydroxycarboxylic acid to the molar concentration of chromium in water-soluble trivalent chromium-containing material is 0.4 or more and less than 2.5. |
