Polyurethane dispersants are described which comprise the reaction product of a polyisocyanate with: a) a component supplying imide-bonding groups in which the carbonyl group of the imide is bonded to a fused or non-fused aromatic ring, b) At least one solvent solubilizing chain, and other optional components for building molecular weight or improving the interaction of the dispersant with the various particles or continuous medium. |
