摘要：
The invention relates to the use of polyurethanes having hyperbranched structures, selected from hyperbranched polyurethanes with at least one group that has an affinity to pigments and modified hyperbranched polyurethanes, as polymer dispersants for pigments. The invention is preferably further characterized in that a hyperbranched polyurethane having 2 to 100 NCO groups and a molecular weight of 500 to 50.000 g is reacted with one or more polyether derivatives.
