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.
