Abstract
Curable mixtures containing (a) a polyepoxide compound having on average more than one epoxide group per molecule and (b) a diamine which contains hydroxyl groups and has the general formula Ia or Ib ##STR1## IN WHICH R is an alkyl radical having 2 to 16 C atoms, an aralkylene radical having 7 to 12 C atoms, an arylene radical having 6 to 16 C atoms, a cycloaliphatic radical having 6 to 12 C atoms or a radical containing at least one N, O or S atom in chains or cyclic groups, and R.sub.1 is a hydrogen atom, a halogen atom or an alkyl group having 1 to 4 C atoms and in which, in formula Ia, the two OH groups are in the orthoposition or para-position relative to the methylene group, there being, in the mixtures, 0.5 to 1.5 equivalents of active hydrogen atoms, which are bonded to nitrogen and oxygen in the diamine containing hydroxyl groups, per 1 equivalent of epoxide groups.
