eng	Vanadium compounds as environmentally friendly driers of alkyd paints	Air-drying binders have been established as a significant group of paints used in modern organic coatings. Presence of double bonds in the binder molecules enables the reaction with air oxygen to give firm coating with three-dimensional polymeric structure. Alkyd resins modified with highly unsaturated fatty acids are able to provide polymeric film without addition of any curing agents but this radical process is generally slow giving the paint film with low final hardness. Nevertheless, the use of metal catalysts, so-called driers, significantly reduces binder drying time and improves physical properties of resulting polymeric film.	vanadium; drier; paint
