Abstract

A cationic resin suitable for use as a pigment grinding vehicle is disclosed. The cationic resin is derived from an epoxy resin and contains ternary sulfonium groups and alkyl phenoxide groups. Pigment pastes derived from this cationic resin can be used in a method of cationic electrodeposition where they provide for films with high build and good appearance.
