CA 2280109
The present invention relates to an aqueous dispersion containing A) a polyol component containing A1) 20 to 60 wt.%, based on the resin solids content of polyol component A), of a polyester resin containing 10 to 60 wt.%, based on the weight of the polyester resin, of one or more aliphatic, saturated or unsaturated monocarboxylic acids having 8 to 30 carbon atoms, and 0.4 to 5 wt.%, based on the weight of the polyester resin, of one or more radically polymerizable .alpha.,beta.-unsaturated mono- or di-carboxylic acids having 3 to 8 carbon atoms, or their anhydrides, and A2) 40 to 80 wt.%, based on the resin solids content of polyol component A), of a polyacrylate, which is prepared in the presence of component A1), and B) 1 to 70 wt.%, based on the resin solids content of the aqueous dispersion, of one or more blocked polyisocyanates. The present invention relates also to the use of the resulting dispersions to prepare stoving coatings, preferably for the initial lacquering of motor vehicles, especially as stoving fillers.
