Abstract

The present invention describes guanidine derivatives of the general formula (I)having the stated meanings for the residues R1, R2 and R3 as accelerators for cold-curing epoxy resin compositions. The curing of cold-curing epoxy resin systems may advantageously be accelerated with the assistance of these compounds.
