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.
