Abstract of the Disclosure Anionic sulphonated polyester are disclosed. They are ob- tained by reaction of (a) at least one n-alkylene, cycloalkylene-, di(alkylene)- arylenediol or polyalkylene glycol. (b) at least one .alpha.,.beta.-ethylenically unsaturated, aliphatic dicarboxylic acid or a functional derivative thereof, (c) at least one saturated, aliphatic, cycloaliphatic or aromatic dicarboxylic acid or a dimeric unsaturated fatty acid which is different from component (b) or a functional derivative of these acids in an initial step and of (d) at least one water-soluble derivative of sulphurous acid or a salt of oxymethanesulphonic acid in a final step. These water-soluble polyesters are useful as dispersant in the manufacture of stable aqueous dyestuffs especially of dyes.
