    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.

    摘要: A process for preparing a reaction product (A), comprising the following stage (i): (i) reacting under free-radical conditions a reaction mixture comprising at least one free-radically reactable monomer (a) in the presence of at least one free-radical initiator and of a compound (I) of the formula:  in which R1 to R4 each independently of one another are hydrogen, a substituted or unsubstituted alkyl radical, cycloalkyl radical or arakyl radical, or an unsubstituted or a substituted aromatic hydrocarbon radical, with the proviso that at least two of R1 to R4 are an unsubstituted or a substituted aromatic hydrocarbon radical in aqueous phase.
