Abstract
A composition, which comprises PA0 (a) a compound containing at least one epoxy group in inner position per molecule, obtained by epoxidation of a natural unsaturated oil or of its derivative; PA0 (b) an epoxy compound selected from the group consisting of glycidyl ethers, glycidyl esters and cycloaliphatic epoxides; PA0 (c) a polycarboxylic acid anhydride; PA0 (d) a compound of formula I, I, III or IV or an acid adduct of a compound of formula I, II, III or IV ##STR1## PA0 wherein R.sub.1 to R.sub.4 are each independently of one another hydrogen; C.sub.1 -C.sub.18 alkyl which is unsubstituted or substituted by one or more than one hydroxyl group amino group, halogen atom, cyano group, C.sub.1 -C.sub.6 alkoxy group or C.sub.1 -C.sub.6 cyanalkoxy group; C.sub.5 -C.sub.14 aryl, C.sub.6 -C.sub.24 aralkyl, C.sub.3 -C.sub.14 heteroaryl or C.sub.4 -C.sub.14 heteroaralkyl which are unsubstituted or substituted by one or more than one C.sub.1 -C.sub.6 alkyl group, C.sub.1 -C.sub.6 alkoxy group or halogen atom, PA0 n is an integer from 1 to 3, and PA0 R.sub.5 and R.sub.6 are each independently of the other C.sub.1 -C.sub.6 alkyl or, together with the nitrogen atom, form a five- or six-membe…
