MANGANESE COMPLEX DRIER FOR COATING COMPOSITIONS

摘要

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=C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue; R1=H, C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms; X=O, OC(R2)O in which a=4 when X=O, and a=3 when X= OC(R2)O, R2= C1-C20 alkyl optionally substituted with heteroatoms, C6-C20 aryl optionally substituted with heteroatoms, or a polymeric residue.
