description The invention relates to curable compositions comprising a) an epoxy resin, b) an aminic curing agent and c) a curing accelerator, which comprise as curing accelerator c) at least one or more than one compound selected from c1) a compound of formula (I) wherein R1 and R2 are each independently of the other a hydrocarbon radical having from 1 to 12 carbon atoms, c2) a reaction product of a compound of formula (I) with formaldehyde, and c3) a reaction product of a compound of formula (I) with formaldehyde and a phenolic compound, in an amount of from 0.1 to 25% by weight, based on the sum of components a), b) and c), and to a process for the production of cured products using those compositions.
