Abstract (en)
[origin: WO0140336A2] An aqueous dispersion of an acrylate modified alkyd resin which can be produced in the following manner in the presence of at least one watermixable diol: 1) at least one alkyd resin containing 0.1. 10 % side or terminal allyloxy groups in relation to the overall quantity thereof, is dispersed in water, resulting in dispersion 1; (2) a mixture of methacrylic acid and at least one other olefinically saturated monomer free of carboxylic acid groups is graft polymerized, resulting in dispersion 2;, and (3) at least one acid-group free olefinically unsaturated monomer and/or at least one mixture of at least one acid-group containing olefinically unsaturated monomer and at least one acid-group free olefinically unsaturated monomer, in which dispersion 2 or 2 n-1 resulting from previous steps (2) or (2) (n-1) is graft polymerized once or n times, with the proviso that acid groups are incorporated in step (3) or repetitions thereof (3) (n), whereby the quantity of said acid groups corresponds to a maximum total of 90 mol % of the acid groups incorporated in step (2).
