Abstract

The invention concerns an aqueous dispersion comprising photocatalytic titanium dioxide particles, an anionic water soluble dispersant of mole weight not more than 5000, and an ampholytic water soluble film-forming polymer whereof the anionic load is not less than the cationic load, the pH of the dispersion being not less than 3.
