The use of an amine of formula (I) as a component of a hardener for epoxy resins, hardeners for epoxy resins containing the amine of formula (I), and resultant epoxy resin compositions which can particularly be used as low-emission room-temperature-curing epoxy-resin coatings with high hardness and surface quality. The amine of formula (I) is low-odour and a very successful diluent for epoxy resin compositions. It is particularly obtained by reductive alkylation from 1,2-ethylenediamine or 1,2-propylenediamine and an aldehyde or ketone.
