Abstract
Colloidal dispersions of solid colloidal particulates in a liquid medium, preferably an aqueous medium, said colloidal particulates comprising a core of cerium oxide at least partially coated with a sheathing layer of titanium oxide, are well suited for the photocatalytic coating of a variety of substrates, e.g., glass or metal, to impart anti-IV, anti-reflecting and/or anti-staining properties thereto.
