Abstract
Storage-stable sols are comprised of a colloidal dispersion of at least one compound of an acidic metal cation, M.sup.n+, for example, cerium (IV) and/or iron (III), in an organic phase which comprises an organic liquid medium and an organic acid. The title sols are conveniently prepared via the phase transfer of colloidal particulates from a counterpart aqueous colloidal dispersion.
