Quaternized oligourethanes, useful as dispersing agents in preparing high-solids pigment concentrates for use in manufacturing inks, especially inks intended for use in gravure and packaging applications. The novel oligourethanes are prepared by reacting an appropriate ester or alcohol with a hydroxyethylimidazoline and polyisocyanate followed by quaternization with acids or alkyl derivatives of acids.
