摘要 A metal treatment solution comprising an effective amount of a soluble or dispersible compound which is a derivative of a polyphenol. The present invention comprises novel derivatives of polyphenol compounds useful in the treatment of the surface of metal articles. The present invention also encompasses novel surface treatment solutions or dispersions, and methods of using these solutions or dispersions. The compositions of the present invention include amine oxide containing polyphenol compounds and derivatives thereof. The molecular weight of the polyphenols used in derivatives of the present invention have molecular weights of from about 360 to about 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.
