Curable compositions of glycidyl compounds, aminic hardeners and novel low viscosity curing accelerators

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.
