Patent ID: 7462658

Claim:
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 R 1 , R 2 , and R 3 independently of one another are identical or different and are hydrogen or a hydroxyl group, and R 1 and R 3 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.
