Abstract

A water-soluble or water-dispersible polyester B useful as emulsifier for aqueous emulsions of alkyd resins A, wherein the polyester B is obtainable by reacting, under polycondensation conditions, polyhydroxyl components Ba from the class of the sugar alcohols having more than 4 carbon atoms and at least five hydroxyl groups per molecule, alkoxypolyethylene glycols Bb having 1 to 4 carbon atoms in the alkyl radical and a number-average molar mass Mn of from 500 to 2000 g/mol, cycloaliphatic dicarboxylic acids Bc and unsaturated or saturated fatty acids Bd having 10 to 22 carbon atoms, a process for its preparation, and alkyd resin emulsions prepared therewith.
