    摘要: The invention relates to a process for preparing a cross-linkable aqueous copolymer dispersion, wherein the process includes (1) polymerizing 5 to 64% by weight of a reaction product of at least one fatty acid having at least one ethylenic double bond and one hydroxyl group in the molecule with a polyalcohol having a hydroxyl functionality of 2 to 8, preferably the triglyceride of ricinoleic acid with 36 to 95% by weight of additional unsaturated monomers, wherein additional unsaturated monomer are polymerized in presence of at least 20% by weight of the total amount of the reaction product as polymerization medium. Aqueous coating compositions containing the aforedescribed aqueous copolymer dispersions show very good drying results compared to known aqueous coating compositions of prior art. In addition coatings therefrom show improved hardness and scratch resistance as well as improved gloss and recoat adhesion.
