Abstract

Cathodically depositable electrodeposition paint binders comprising the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, optionally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde. The binders have excellent corrosion resistance and crosslink to provide coating films at relatively low stoving temperatures without splitting off of substances harmful to the environment.
