    摘要： In a liquid coating composition comprising a small amount of solvent or no solvent, a binder and optionally conventional auxiliary agents, wherein the binder consists essentially of:(A) 45-10% by weight of an aminoplast, the low molecular weight precursors thereof, or mixtures thereof; and(B) 55-90% by weight of an at least difunctional polyester or a mixture of such polyesters; wherein the polyester component B has been produced by the condensation of a conventional alcohol component I with an acid component III, wherein component III consists essentially of a mixture of:III.1 67-92 molar percent of hexahydroterephthalic acid or a lower alkyl ester thereof; andIII.2 8-33 molar percent of an aromatic dicarboxylic acid or a lower alkyl ester derivative thereof;wherein the polyester component B has a molecular weight of 300-1,500 and wherein the binder may be obtained by the cocondensation of aminoplast component A with polyester component B, or by the cocondensation of the starting materials used for the production of aminoplast component A with polyester component B;the improvement wherein component III.2 is terephthalic acid or a lower alkyl ester derivative thereof.

    摘要： Liquid, highly pigmentable coating compositions containing little or no solvent and which are suitable for spray coating employ a binder consisting either ofA. 45-10% by weight of an aminoplast, a low-molecular weight precursor thereof, or a mixture thereof, andB. 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.
