An air drying auto-oxidizable resin composition comprising components: a) a drier comprising a manganese salt complex, and b) a polymer comprising unsaturated fatty acid residues, wherein the manganese salt complex has the following structure I: wherein the anion is selected from Cl, NOor RCOO, in which case n=2; or the anion is SO, in which case n=1; wherein X,Y,Z are independently selected from O, OH, OH, OC(R)O, and RBOand wherein a and b are independently an integer of value 2, 3 or 4; R&#x2550;H, C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms; R=C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue; and R=C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue. R&#x2550;C1-C20 alkyl optionally substituted with heteroatoms, or C6-C20 aryl optionally substituted with heteroatoms. 

Manganese salt complex as drier for coating compositions

An air drying auto-oxidizable resin composition comprising components: a) a drier comprising a manganese carboxylate complex, and b) a polymer comprising unsaturated fatty acid residues, wherein the manganese carboxylate complex a) has the following structure I: wherein R&#x2550;H, C1-C20 alkyl optionally substituted with heteroatoms, or C6-C20 aryl optionally substituted with heteroatoms; X and Y are independently selected from O and OC(R)O, in which a=4 when X&#x2550;O, and a=3 when X&#x2550;OC(R)O, and in which b=4 when Y&#x2550;O, and b=3 when Y&#x2550;OC(R)O; R=C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue; and R&#x2550;C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue. 

Manganese complex as drier for coating compositions

Use of a transition metal complex a) as a drier for air drying auto-oxidative resin composition comprising a polymer b) comprising unsaturated fatty acid residues, wherein the transition metal complex a) has a cation of the following structure (I) wherein R&#x2550;C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue; R&#x2550;H, C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms; X&#x2550;O, OC(R)O in which a=4 when X&#x2550;O, and a=3 when X&#x2550;OC(R)O, R&#x2550;C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue.
