Abstract: The invention concerns a composition for use as drier in auto-oxidizable coatings or as accelerator in unsaturated polyester resins, comprising a manganese-bearing polymer having a manganese dicarboxylate repeating unit and at least one nitrogen-containing donor ligand. Such compositions offer excellent drying performances. They ensure a strongly reduced leachability of manganese compared to that of known manganese-bearing driers.
