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; and III.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.
