Abstract
A pigment paste suitable for use in cationic electrodeposition is disclosed. The pigment paste comprises a cationic resinous grinding vehicle derived from an epoxy resin containing both quaternary ammonium and ternary sulfonium salt groups. Also disclosed are cationic electrodeposition paints containing the pigment paste and the use of these paints in the process of cationic electrodeposition. The paste improves the stability of lead-containing cationic electrodeposition paints.
