A surface treatment for metal, prepared by adding a cationic or nonionic,. urethane, acrylic, epoxy, polyester, or polyamide resin, a resin compound represented by the general formula (I), and a compound of Zr, Ti, V, Mo, W, Mn, or Co to water; a process for surface treatment of metallic substances, and surface-treated metallic substances: (I) Äwherein R<1> is -CH2-, CH2-NH-CH2-, or -CH=N-CH2-Y is H or a group represented by the general formula (II)-(II) Z is a residue of an aromatic compound or the like; W is H or a group (P) selected from among -CH2X, -CH2NHCH2X, and -CH=NCH2X (wherein X is OH, OR<4>, halogeno, -N(R<5>)(R<6>), or -N<+>(R<7>)(R<8>(R<9>)A<->), with the proviso that the degree of substitution with the group (P) satisfies the relationship: (member of Ps)/(total number of benzene rings and Zs) = 0.2 to 4.0; n is 0 to 10). The surface treatment is free from chromium and can import excellent corrosion resistance, alkali resistance and fingerprinting resistance to metallic substances.
