Abstract
The present invention relates to a drier composition (DC) for use in a coating composition preferably in an autoxidizable alkyd based coating composition (AC). The drier composition (DC) comprises: (a) At least one metal complex (MC) comprising: at least one metal salt (MS) comprising at least one metal cation (M) which is selected from the group consisting of iron (Fe) and manganese (Mn) and at least one anion (AN) and at least one nitrogen donor ligand (L) which is selected from the group comprising monodentate, bidentate, tridentate, pentadentate, and hexadentate nitrogen donor ligands, and (b) at least one non-ionic emulsifier (E). The present invention is further directed to an autoxizable alkyd based coating composition (AC) comprising said drier composition (DC), to the use of said autoxizable alkyd based coating composition (AC) and also to a substrate coated with said autoxizable alkyd based coating composition (AC).
