ABSTRACT:
A polyphenol compound wherein the aromatic rings are linked by direct bonds or by a divalent link in the ortho position relative to the --OH group and the end aromatic rings contain either oximino substituents or substituted alkylaminomethyl substituents in the ortho position. The compound can be coated onto a metal surface to give improved corrosion resistance. The metal surface can be zinc-coated steel or zinc phosphated steel. The polyphenol compound can be the only coating material or can be incorporated into a surface coating composition such as a paint.
