Abstract

Amino group containing curing component (A) for compounds (B) which contain epoxy or 1,3-dioxolan-2-one groups, comprising a reaction product of (a.sub.1) active CH alkyl esters of isocyanate adducts thereof with (a.sub.2) polyamines. Mixtures of (A) and (B) with or without diluents and additives give rapid curing even at low temperatures and high atmospheric humidity and are suitable in particular for paint formulations.
