    Abstract: Curable composition for antiabrasion coating, including the constituents A - a hydrolysate of an epoxytrialkoxysilane, B - a hydrolysate of a silane of formula (I) in which each of T and T produces an OH group by hydrolytic treatment and Z and Z are unreactive organic groups, C - colloidal silica, D - a specific aluminium catalyst, E - optionally, an organic solvent whose boiling point is between 70@C and 140@C, and the corresponding coated articles, optionally treated against reflections.

    Abstract: The invention relates to methods for obtaining the photochromic latex comprising the polymerization in aqueous emulsion of an initial polymerizable mixture, comprising one or more monomers polymerizable by free-radical mechanism and one or more photochromic compounds and the addition to the initial polymerizable mixture, during the polymerization of the initial polymerizable mixture or to the final latex of at least one agent for stabilizing the photochromic properties. Such latexes can be used in the production of photochromic films. Such films may be used, for example, on optical lenses.
