Abstract of the Disclosure A quaternary ammonium group-containing material and its method of preparation are disclosed. The quaternary ammonium group contains at least one organic group which contains an acyclic group of at least 8 carbon atoms and also contains a group of the structure - ? - ? - wherein R1 is hydrogen or lower alkyl. The quaternary ammonium group-containing materials are useful as pigment grinding vehicles and in the formulation of pigment paste, particularly pigment paste with high pigment loadings. When formulated in cationic electrodepositable compositions, the pigment grinding vehicles provide for cured electrodeposited coatings of excellent corrosion resistance, particularly over untreated and oily steel.
