Abstract
Disclosed herein is a cathodic electrodepositable resin containing polyamine enamine. It has been discovered that reacting epoxy resins with polyamine enamine is a viable method of introducing amine functionality to the epoxy resin. The polyamine enamine route results in the desired high pH and stable dispersion in the electrocoat bath.
