A metal treatment solution comprising an effective amount of a soluble or dispersible compound which is a derivative of a polyphenol. A composition for treatment and after treatment of metal with polyphenol compounds is provided. The present invention includes novel derivatives of polyphenol compounds which are useful in surface treatment solutions or dispersions. A method for using these solutions or dispersions is also provided. The molecular weight of the polyphenols used to form the derivatives of the present invention are in the range of from about 360 to 30,000 or greater. The resulting derivatives of the present invention typically have a molecular weight of up to about 2,000,000 with molecular weights within the range of about 700 to about 70,000 being preferred.
