摘要

The invention pertains to a drier composition for air-drying alkyd-based coatings, inks, or floor coverings, comprising a combination of the following components: a) a transition metal salt with the formula: (Meⁿ⁺)(X^k-)_m in which Me is the transition metal; X^- represents a coordinating ligand; and k- is the valence state of the transition metal and m is the number of ligands X. b) a reducing biomolecule. The reducing biomolecule is in particular ascorbic acid or a derivative thereof, including ascorbyl palmitate.
