A metal surface is treated by contacting the surface with a solution comprising an effective amount of a soluble or dispersible treatment compound selected from the group consisting of a polymer having the following general formula, acid salts thereof, and mixtures thereof: where: R1 through R3 are hydrogen or an alkyl group having from 1 to about 5 carbon atoms; each Y is hydrogen, Z, CR4R5OR6, Ci2C1, or an alkyl or aryl group having from 1 to 18 carbon atoms; R4 through R10 are hydrogen or an alkyl, aryl, hydroxy-alkyl, amino-alkyl, mercapto-alkyl or phospho-alkyl moiety, said R4 through R10 being of carbon chain lengths up to a length at which the compound is not soluble or dispersible; and n is from 2 up to a number at which polymer is not soluble or dispersible ; with the proviso that R1, R2 and R3 cannot simultaneously represent hydrogen when the substituted vinyl group is para to the hydroxyl moiety. |
