Abstract

A treatment solution for contacting a metal surface comprises: PA1 from about 0.001% to about 1.0% of a metal ion selected from the group consisting of titanium, zirconium and hafnium and mixtures thereof; and PA1 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: ##STR1## where: R.sub.1 through R.sub.3 are hydrogen or an alkyl group having from 1 to about 5 carbon atoms; PA1 each Y is hydrogen, Z, CR.sub.4 R.sub.5 OR.sub.6, CH.sub.2 Cl, or an alkyl or aryl group having from 1 to 18 carbon atoms; PA1 Z is ##STR2## R.sub.4 through R.sub.10 are hydrogen, or an alkyl, aryl, hydroxy-alkyl, amino-alkyl, mercapto-alkyl or phospho-alkyl moiety, said R.sub.4 through R.sub.10 being of carbon chain lengths up to a length at which the compound is not soluble or dispersible; and PA1 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 above …
