Abstract
Abstract 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: <IMAGE> where: R1 through R3 are hydrogen or an alkyl group having from 1 to about 5 carbon atoms; each Y is hydrogen, Z, CR4R5OR6, CH2Cl, or an alkyl or aryl group having from 1 to 18 carbon atoms; Z is <IMAGE> 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 the polymer is not soluble or dispersible. Preferably, the solution is an aqueous solution and "Z" moieties are present in sufficient amount that the compound is water soluble or water dispersible. Metal surfaces contacted with the solution have enhanced corrosion resistance and paint adhesion characteristics.
