  The present invention relates to curatives for epoxy resins, and compositions (e.g. adhesives) containing such resins cured using the same methods of preparation and uses therefor. More specifically, the present invention relates to hybrid curatives for epoxy resins comprising both aromatic amine, phenol and/or phenyl ester moieties. A further aspect of the current invention relates to new imidazole catalysts that possess a combination of excellent cure latency as well as low cure temperature onset.
