Abstract (en)
[origin: WO2004020503A1] The invention relates to a method for the production of essentially non-cross-linked, hyperbranched polyesters which are soluble or dispersible in water, from dicarboxylic acids and polyether polyols which have at least three 3 OH groups. The invention further relates to water-soluble hyperbranched polyesters produced by such a method and the use thereof for the production of printing inks, adhesives, coatings, paints and finishes.
