Zusammenfassung:Liquid, highly pigmentable coating compositions containing little or no solvent and which are suitable for spray coating employ a binder consisting either of A. 45-10% by weight of an aminoplast, a low-molecular weight precursor thereof, or a mixture thereof, and B. 55-90% of an at least bifunctional polyester, or a mixture thereof, having predominantly hydroxy end groups, a degree of condensation of between 2.5 and 10.5 and a molecular weight of up to 1,000, and prepared by condensing an alcohol component consisting of 0-30 molar percent of one or more 3-6 carbon atom polyols having 3-4 hydroxy groups and 100-70 molar percent of a mixture of diols consisting of 33-90 molar percent of ethylene glycol and 67-10 molar percent of 1,2-propanediol, or a condensation product of A and B.
