Abstract:
A process for preparing a coated substrate which comprises coating the substrate with an aqueous dispersion comprisingA) a polyol component comprisingA1) 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, andA2) 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), andB) 1 to 70 wt. %, based on the resin solids content of the aqueous dispersion, of one or more blocked polyisocyanates. for light-stable, elastic and physically rapidly drying coatings in the series lacquering of motor vehicles,and physically curing the dispersion to form a coating.
