Aqueous-based mixtures comprising colloidal vanadium oxide and a dispersed sulfonated polymer impart antistatic properties to coatings on a substrate and to self-supporting articles. The preferred colloidal vanadium oxide is alkoxide derived and provides mixed valence vanadium oxide wherein the vanadium ions are typically +4 and +5. Preferred sulfopolymers include sulfopolyesters, sulfopolyurethanes, sulfopolyurethanes/ureas, sulfopolyester polyols, and sulfopolyols. Antistatic composite structures comprising colloidal vanadium oxide and a sulfopolymer are also disclosed.
