Paints containing alkyd resins need catalysts for oxidative curing. Because of the probable reclassification of the widely used cobalt carboxylates as carcinogens there is interest in alternative alkyd paint drying catalysts. Various manganese and iron paint driers with polydentate ligands have recently been reported; a particular iron-based catalyst shows good paint drying activity at low dosage.
