Abstract

In the present application, addition compounds of hydroxyalkylimidazolines, aromatic or araliphatic diisocyanates and polyols are described and claimed, as are their preparation by reaction, initially of two reactants and then with the third, optionally in an inert solvent, and the use of these addition compounds as dispersants for solid materials in non-aqueous liquids, in particular pigment dispersions.
