    Abstract: The present invention relates to a process for preparing a coated, heat resistant substrate byI) coating the substrate with a coating composition containinga) a solution or dispersion containinga1) 100 parts by weight of at least one hydroxyl-functional polyacrylate resin in dissolved or dispersed form, wherein the resin has a hydroxyl value of 15 to 200 mg KOH/G solid resin, an acid value of 5 to 250 mg KOH/G solid resin and a total content of chemically incorporated carboxylate and/or sulfonate groups of 8 to 450 milliequivalents per 100 g of solids,a2) 25 to 395 parts by weight of water anda3) 5 to 125 parts by weight of at least one organic solvent having a boiling point or boiling range at 1013 mbar of 100 to 300.degree. C. andb) at least one organic polyisocyanate in a quantity corresponding to an equivalent ratio of isocyanate groups of component b) to isocyanate-reactive groups of component a1) of 0.7:1 to 3:1, andII) curing the coating composition at a temperature of 40 toThe present invention is also directed to the coated substrates obtained by this process.
