The present invention relates to epoxy curing agent compositions comprising naphthol and naphthol derivatives in combination with at least one polyamine having three or more active amine hydrogens, and use of these curing agents as hardener for epoxy resins. These curing agent compositions may be used to cure, harden and/or crosslink an epoxy resin. La présente invention concerne des compositions d'agent de durcissement d'époxy comprenant du naphtol et des dérivés de naphtol en combinaison avec au moins une polyamine ayant au moins trois hydrogènes d'amine actifs, et l'utilisation de ces agents de durcissement en tant que durcisseurs pour des résines époxy. Ces compositions d'agent de durcissement peuvent être utilisées pour durcir et/ou réticuler une résine époxy.
