Abstract

The present invention describes the use in epoxy resin compositions of semicarbazones of the general formula (I) having the meanings stated for the residues R1, R2, R3 and R4.These semicarbazones exhibit elevated latency in epoxy resin compositions and are thus outstandingly suitable as latent curing accelerators for single-component epoxy resin compositions.
