Claim:
1. A method of preparing an oxidatively curable coating composition, comprising contacting a formulation with a composition comprising manganese, iron, or vanadium ions, so that the composition comprises a concentration of between about 0.0003 wt % and about 0.07 wt %, of one ion selected from manganese, iron and vanadium ions, wherein said formulation comprises: (1) an oxidatively curable alkyd-based resin, (2) less than 0.0001% by weight of ions of each of manganese, iron, cobalt, vanadium and copper, and, (3) a chelant capable of chelating at least one transition metal ion through either two or three nitrogen atoms, wherein said chelant has a concentration, with respect to said oxidatively curable alkyd-based resin, of between about 0.0005 and about 5 wt %, and is of formula (I): wherein: p is 3; R is independently selected from the group consisting of hydrogen, C R
