Abstract:
An aqueous alkyd resin emulsion having a mass fraction of an alkyd resin A in the solids of the emulsion of from 70 to 95% and a mass fraction of a polyester B or from 5 to 30%, the mass fractions adding up to 100%, wherein the polyester B is obtained 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, alkoxypolyothylene 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, and where the mass fractions in the mixture of starting materials of the polyester B are from 10 to 40% of the polyhydroxyl component Ba, from 35 to 70% of the alkoxypolyethylene glycol Bb, from 10 to 30% of the cycloaliphatic dicarboxylic acid Bc, and from 15 to 40% of the fatty acid Bd.
