Abstract
The invention relates to an aqueous dispersion of a modified alkyd resin comprising water, an emulsifier S a copolymer P having moieties derived from one or more of esters M1 of an olefinically unsaturated carboxylic acid M11 having at least one olefinic unsaturation and at least one acid group per molecule, with a linear, branched or cyclic aliphatic hydroxy-functional compound M12 having at least one hydroxyl group per molecule, esters M2 of an olefinically unsaturated hydroxy functional compound M22 having at least one olefinic unsaturation and at least one hydroxyl group per molecule, with linear, branched or cyclic aliphatic carboxylic acid M21 having no olefinic unsaturation and at least one acid group per molecule, an olefinically unsaturated carboxylic acid M11 having at least one olefinic unsaturation and at least one acid group per molecule, an olefinically unsaturated hydroxy functional compound M22 having at least one olefinic unsaturation and at least one hydroxyl group per molecule, an olefinically unsaturated compound M3 that has at least one olefinic unsaturation, selected from the group consisting of olefinically unsaturated alkylaromatic compounds M31, olefinicall…
