A drier for air-drying an auto-oxidizable resin composition, said drier comprising: 1,4,7-trialkyl- 1,4,7-triazacyclononane (L); a manganese salt having the general formula Mn2+[X]n, wherein anion X is selected from PF6 -, SbF6 -, AsF6 -, BF4 -, B(C6F5)4 -, CI-, Br-, I-, NO3, or R2COO- in which case n=2, or the anion X is SO4 2- in which case n=1, and wherein R2 is C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 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 Mn:L is at least 1.25:1 and preferably at least 1.5:1. |
