Zusammenfassung:The present invention provides a method for producing water-soluble polyurethane epoxy cation resin for thick-coating cathodic electrophoresis paint. The invented resin is characterized by directly connecting semi-blocked polyisocyanate to molecular chain of epoxy resin. The semi-blocking agent for polyisocyanate is a compound containing "active hydrogen", for example isopropanol and so on.
