ABSTRACT:
The present invention relates to compositions containing (a) at least one compound having at least one 1,2-epoxide group in its molecule and (b) at least one compound of the formulae I, II, III or IV ##STR1## in which m and n independently of one another are 1 or 2, y is an integer from 2 to 10, p is 3 or 4, R.sup.1, R.sup.3 and R.sup.4 are derived from radicals of aliphatic, cycloaliphatic or aromatic carboxylic acids, R.sup.1 being a divalent or trivalent radical, R.sup.3 being a divalent radical and R.sup.4 being a trivalent or tetravalent radical, after the removal of the carboxyl groups, R.sup.5 is a divalent radical of an aromatic hydroxycarboxylic acid after the removal of the carboxyl group and of the phenolic hydroxyl group and R.sup.2 is the radical of an aliphatic or cycloaliphatic diol after the removal of the two hydroxyl groups, subject to the proviso that at least 70% by weight of the radicals R.sup.1 or R.sup.3, relative to the total amount of these radicals, are derived from dimeric and/or trimeric fatty acids, that at least 70% by weight of the radicals R.sup.2, relative to the total amount of these radicals, are groups of the formula V
