Abstract
The present invention relates to an oxidatively curable coating formulation comprising an oxidatively curable alkyd-based resin and a chelant capable of chelating at least one transition metal ion through either three or four nitrogen atoms, which chelants may each optionally be complexed with one or two transition metal ions, typically iron or manganese ions. The formulations may be paints or other oxidatively curable coating compositions. The invention also provides methods for making such formulations and compositions resultant from the curing of such formulations.
