Curable powdry mixtures

Abstract

Abstract Curable, pulverulent mixtures of A) carboxyl-containing polyesters, B) compounds which contain at least two 1,2-epoxide groups and are products of the reaction of B1) compounds containing at least two 1,2-epoxide groups per molecule and having epoxide equivalent weights of from 160 to 600 and B2) aromatic dicarboxylic acids or mixtures thereof with compounds from the group comprising (cyclo)aliphatic dicarboxylic acids, monocarboxylic acids and/or monohydric phenols, and B3) optionally cyclic anhydrides, and C) optionally conventional additives, are distinguished, in particular, by improved yellowing resistance and/or increased reactivity.
