Abstract
There are described novel imidazolides (N-acylimidazoles) of the formula I ##STR1## wherein R.sub.1 is methyl, ethyl or isopropyl, PA1 R.sub.2, R.sub.3 and R.sub.4 independently of one another are each hydrogen, methyl, ethyl or isopropyl, with the proviso that R.sub.2 is hydrogen only when R.sub.1 is isopropyl, PA1 R.sub.5, R.sub.6 and R.sub.7 independently of one another are each hydrogen, methyl, ethyl or isopropyl, or phenyl which is unsubstituted or substituted by methyl or ethyl groups, with the proviso that at least one of the symbols R.sub.5, R.sub.6 and R.sub.7 is phenyl which is unsubstituted or substituted according to definition. The imidazolides (I) are suitable as curing agents for polyepoxide compounds.
