Abstract
Curable compositions based on epoxy resins or a mixture of epoxy resins and polyisocyanates and containing at least one compound of formula I: ##STR1## wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7, R.sub.8 and R.sub.9 are each independently of one another hydrogen, alkyl, aryl, arylalkyl or halogen, and R.sub.2 together with R.sub.3 and R.sub.5 together with R.sub.6 and R.sub.8 together with R.sub.9 may each also represent a fused benzene ring. The compositions have high reactivity and at the same time good storage stability.
