A composition for treating metal surfaces that contains, at a weight ratio from 1:5,000 to 5,000:1, at least one metal acetylacetonate selected from the group consisting of Al(C5H7O2)3, V(C5H7O2)3, VO(C5H7O2)2, Zn(C5H7O2)2, and Zr(C5H7O2)4, and at least one compound selected from water-soluble inorganic titanium compounds and water-soluble inorganic zirconium compounds provides a non-chromate-type composition for imparting an excellent corrosion resistance and paint adherence to the surfaces of metals, particularly aluminum and its alloys, magnesium and its alloys, and zinc and its alloys. |
