ABSTRACT:
Process for preparing essentially uncrosslinked hyperbranched, water-soluble or water-dispersible polyesters from dicarboxylic acids and polyether polyols having at least 3 OH groups. Water-soluble hyperbranched polyesters which are obtainable by such a process and their use for producing printing inks, adhesives, coatings, paints and varnishes.
