1. A curable composition comprising a curable component and at least one m-hydroxybenzene derivative of the general formula
(I):
 where Y is a carboxyl group, a carboxylate group or a straight-chain or branched alkyl group optionally substituted by hydroxyl
groups, amino groups, carboxyl groups and/or carboxylate groups;
and R1, R2, and R3 independently of one another are identical or different and are hydrogen or a hydroxyl group, and R1 and R3 are not simultaneously a hydroxyl group;
wherein the m-hydroxybenzene derivative of the general formula (I) is in interaction with iron(III);
with the provisos that, where the curable component is a thermosetting component of a multicomponent, epoxy-based system,
the curable composition is free from transition metal oxides of the copper group and zinc group and that, where the curable
component is an epoxy-based thermosetting component, the curable component is not a self-curing component.
