    Abstract: The invention relates to branched polyesters with sulfonate groups. The polyesters can be obtained by reacting the components A, B, optionally C, and optionally D into branched polyesters, wherein the component A is selected from the group consisting of the α,β-olefinically unsaturated dicarboxylic acids, the component B is selected from the group consisting of the tri- or higher-functional alcohols, the optional component C is selected from the group consisting of the difunctional alcohols or the difunctional carboxylic acids without α,β-olefinically unsaturated bonds, and the optional component D is selected from fatty acids or fatty alcohols. The obtained branched polyesters are subsequently reacted with hydrogen sulfite, the molar quantity of hydrogen sulfite being at most 95 mol% with respect to the quantity of α,β-olefinically unsaturated dicarboxylic acid.
