ABSTRACT OF DISCLOSURE Cathodically depositable electrodeposition paint binders comprising a mixture of (A) 95 - 50% by weight of the reaction product of an epoxy resin with at least two epoxy groups with amines carrying primary amino groups and, option- ally, with a carboxylic acid compound to provide an epoxy resin-amino adduct which is then reacted with a phenol and formaldehyde; and (B) 5 - 50% by weight of an addition com- ponent which is substantially water-insoluble under the con- ditions of electrodeposition and being compatible with Compo- nent A. The presence of Component B in the binder provides increased resistance to corrosion, improvements in the surface quality of the stoved films, and enhanced crosslinking of the binder.
