Abstract
The present invention relates to an aqueous dispersion obtained by a process comprising the steps of (a) preparing an acidic copolymer (A) by radical copolymerization of monomers comprising: (a1) at least one unsaturated fatty acid, (a2) at least one ethylenically unsaturated monomer containing at least one acid group or group capable of forming an acid group, (a3) at least one other ethylenically unsaturated monomer different from (a1) and (a2), (b) neutralizing totally or partially the acid groups of copolymer (A) and dissolving it in water, (c) copolymerizing in the solution obtained at step (b) a monomer mixture different from the monomer mixture of step (a) to form a copolymer (B) as well as blends based on such dispersions, especially in combination with oxidatively drying alkyds.
