Imidazoline compounds of formula ##STR1## where n denotes 2 or 3, is suitable as cure accelerator in curable epoxide resin compositions comprising a latent curing agent.

Imidazoline compounds

Adducts of the formula I ##STR1## are described in which R.sup.1 is an e-valent aliphatic radical after the removal of the functional groups, X is --O--or --NH--, R.sup.2 is a d+l-valent carbocyclic-aromatic radical, R.sup.3 is hydrogen or methyl, R.sup.4 is an aliphatic, aromatic, or araliphatic c+l-valent radical, Y is --O--, --S--or --NR.sup.5 --, R.sup.5 is hydrogen or ##STR2## b is an integer from 2 to 15, b is an integer from 1 to 25, c is 1, 2 or 3, d is 1, 2 or 3 and e is 2, 3 or 4. The adducts can be combined with latent curing agents and, if appropriate, other epoxy resins to give adhesives having good stability on storage and high flexibility.
