A hardenable epoxy resin comprising a curable epoxy resin, a hardener for the epoxy resin and a polymer of epihalohydrin which composition is characterized in that the amount of the polymer of epihalohydrin in the composition is from 1 to 6 parts per one hundred parts by weight of the epoxy resin and in that the composition also comprises from 2 to 25 parts by weight per hundred parts by weight of the epoxy resin, of a polycarbonate having the general formula: <IMAGE> where R1 and R2 are the same or different and are phenyl or cyclohexyl groups, R3 and R4 are the same or different and are hydrogen, methyl or cyclohexyl groups and n is from 60 to 400 and represents the average number of monomer units in the polymer chain.
