Abstract:
The invention relates to a drier composition for an autoxidizable alkyd based coating composition, comprising: a) at least one Fe complex comprising Fe and at least one nitrogen donor ligand, wherein the nitrogen donor ligand is selected from tridentate, tetradentate, pentadentate and hexadentate nitrogen donor ligands; b) at least one metal salt of a carboxylic acid, wherein the metal is selected from Mn, Ce, V, and Cu; and c) at least one ligand comprising at least one moiety selected from 1,4,7-tri-azacyclononanyl, 2,2′-bipyridyl, 1,10-phenantrolinyl, imidazolyl, pyrazolyl, porphyrinyl, aliphatic, cycloaliphatic, and aromatic amines. The present invention also relates to coating composition comprising the drier composition, and a method of reducing skinning tendency of an autoxidizable alkyd based coating composition while accelerating drying time thereof upon application of the autoxidizable alkyd based coating composition to a substrate as a coating, comprising adding the above drier composition to the autoxidizable alkyd based coating composition.

Claim (Index 6):
The drier composition according to  claim 1 , wherein the at least one ligand in c) is a compound of formula (V), wherein each R 20  is independently selected from the group consisting of C 1-6 alkyl, C 3-8 cycloalkyl, heterocycloalkyl, heteroaryl, C 6-10 aryl and C 6-10 aryl-C-6alkyl, each group being optionally substituted with one or more substituents each independently selected from the group consisting of \u2014OH, C 1-6 alkoxy, phenoxy, carboxylate, carboxamide, carboxylic ester, sulfonate, amine, C 1-6 alkylamine and \u2014N + (R 21 ) 3 ; each R 21  is selected from \u2014H, C 1-6 alkyl, C 2-6 alkenyl, C 6-10 aryl-C 1-6 alkyl, C 6-10 aryl-C 2 -6alkenyl, C 1-6 alkyloxy, C 2-6 alkenyloxy, aminoC 1-6 alkyl, aminoC 2-6 alkenyl, C 2-6 alkyl ether, C 3-6 alkenyl ether, and \u2014CX 2 2 -R 22 ; each X 2  is independently selected from \u2014H and C 1-3 alkyl and wherein each R 22  is independently selected from an optionally substituted heteroaryl group selected from the group consisting of pyridyl, pyrazinyl, pyrazolyl, pyrrolyl, imidazolyl, benzimidazolyl, pyrimidinyl, triazolyl and thiazolyl; and, wherein at least one of R 21  is \u2014C(X 2 ) 2 \u2014R 22 .
