Abstract
Hydrazides of the formula ##STR1## are good curing agents for epoxy resin, in the formula R.sub.1 and R.sub.2 being each hydrogen atom, C.sub.1 -C.sub.8 alkyl radical or --CH.sub.2 CH.sub.2 SCH.sub.3, R being hydrogen atom or methyl radical. The curing agents are useful in formulating novel storable one-package, heat-curable epoxy resins-based compositions.
