ABSTRACT:
The invention relates to new imidazolyl derivatives, their use as curing agents in epoxy-resin compositions, and curable epoxy-resin compositions containing them and composed of an epoxy resin and compounds of the general formula ##STR1## where R is the group of the alcohol component used to produce the glycidyl ethers, R.sup.1 and R.sup.2 are, independently of each other, hydrogen, --CH.sub.3 or --C.sub.2 H.sub.5, n is 2 or 3, R.sup.3 is COOH, --CH, --COHN--N.sub.H2, --COOCH.sub.2 --CH.sub.2 --OH or COOR.sup.4, R.sup.4 being an aliphatic hydrocarbon group having from 1 to 4 carbon atoms, and m is equal to the valence of R.
