A mixture for use as a drier for air-drying an auto-oxidizable resin composition, said mixture comprising: 1,4,7- trialkyl-1,4,7-triazacyclononane (L); and, a manganese salt having the general formula Mn 2+ [X] n , wherein anion X is selected from PF 6 - , SbF 6 - , AsF 6 - , BF 4 - , B(C 6 F 5 ) - , Cl - , B - , I - , NO 3 - , or R 2 COO - in which case n=2, or the anion X is SO 4 2- in which case n=1, and wherein R 2 = C 1 -C 20 alkyl optionally substituted with heteroatoms, C 6 -C 20 aryl optionally substituted with heteroatoms, or a polymeric residue; wherein the 1,4,7- trialkyl-1,4,7-triazacyclononane (L) is present in the mixture in an amount such that the molar ratio of L: Mn is greater than 1:1, preferably at least 1.25: 1 and more preferably at least 1.5: 1. |
