Abstract: A composition for treatment and after treatment of surfaces, especially metals, with derivatives of polyphenol compounds is provided. The derivatives include substituted aminomethyl groups on at least some of the phenyl rings in the polyphenol polymers, with molecular weights within the range of about 700 to about 70,000 being preferred. The compositions are particularly useful for treating chromated aluminum surfaces prior to painting, to improve corrosion resistance, and when combined with surfactants, for treating plastic and painted surfaces to improve rinsability without water breaks.

Abstract: A treatment solution for contacting a metal surface comprises: 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 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, CH2Cl, or an alkyl or aryl group having from 1 to 18 carbon atoms; Z is 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 above treatment solution have enhanced corrosion resistance and paint adhesion characteristics.
