Abstract
Heat-curable mixtures containing (a) epoxy compounds having on average more than one 1,2-epoxy group per molecule, (b) monoimides or polyimides of specific unsaturated dicarboxylic acids of the formula I ##STR1## wherein A is an x-valent aromatic or aliphatic radical, R.sup.1 is hydrogen or methyl, and x is 1, 2 or 3, and (c) products of condensing specific phenols, specific amines and aldehydes or ketones in an acid medium. The novel curable mixtures have a long shelf life and give rise to moulded materials which are highly resistant to chemicals and resistant to boiling water.
