    摘要: Disclosed is a dispersant obtainable by reacting (i) a di- or polyfunctional isocyanate with (ii) an HX-terminated polymeric compound, where X is COO, O, S or NR1 and R1 is H or C1-C6-alkyl; and either (iii) an HY-terminated homopolymer of a monomer selected from the group consisting of N-vinylamides, N-vinyllactams and vinyl- or allyl-substituted nitrogenous heterocycles or copolymer of one or more of the monomers mentioned and optionally further monomers, where Y is COO, O, S or NR2 and R2 is H or C1-C6-alkyl; or (iv) an HY-functional organic phosphonic ester, where Y is as defined above. The dispersant is especially useful for dispersing pigments and for preparing inkjet inks.
