An aqueous solution comprising an effective amount of a water soluble or water dispersible compound selected from the group consisting of a polymer having the following general formula, acid salts thereof and mixtures thereof: ##STR1## where: n=from 2 up to a number at which the polymer is not water soluble or water dispersible; n X=H or Z; ##STR2## Y=H, Z, Cr 5 R 6 OR 7 , or CH 2 Cl; R 1 through R 7 =H, or an alkyl, aryl, hydroxy-alkyl, amino-alkyl, mercaptoalkyl or phospho-alkyl moiety, said R 1 through R 7 being of carbon chain lengths up to a length at which the compound is not water soluble or dispersible; n wherein at least one of X or Y=Z and the Z moieties are present in sufficient amount that the compound is water soluble or water dispersible. n This solution is useful in the treatment of metal surfaces to impart corrosion resistance and paint adhesion characteristics thereto. |
