Abstract of the Disclosure Curable mixtures comprising a polyepoxide compound having on average more than one epoxide group per molecule and a 1,3- diaminopropane of the formula Image wherein R1 denotes hydrogen and R1, R2 R3 and R4 each denote an alkyl having 1 to 12 C atoms, a phenyl or a heterocyclic 5-membered or 6-membered radical, or wherein R1 and R2 together with the C atom in the .alpha.-position of the propylenediamine form a substituted or unsubstituted aliphatic 5-membered or 6-membered ring having at most 12 C atoms and R3 and R4 together with the two C atoms in the .alpha.-position and the .alpha.-position of the pro- pylenediamine form a substituted or unsubstituted aliphatic or N-heterocyclic 5-membered or 6 membered ring having at most 12 C atoms, said mixtures containing 0.5 to 1.5 equivalents of active hydrogen atoms, bonded to nitrogen, in the 1,3-diaminopropane per 1 equivalent of epoxide groups in the epoxide compound. The curable mixtures are valuable casting resins and adhesives and are suitable for the preparation of storable B-stage resins.
