A composition includes: a continuous liquid phase including an acrylic monomer and an epoxy monomer; and a dispersed nanoparticulate including ZrOmodified with an acrylic silane; and wherein the composition is transparent to visible light when coated on a lens. In addition, a method including the steps of: mixing an acrylic silane and a methanol-based ZrOsol to create a methanol-based silane-modified ZrOsol; then mixing at least an acrylic monomer, an epoxy monomer, and the methanol-based silane-modified ZrOsol to obtain the composition. The composition can be adapted for coating and curing onto another substrate, such as an ophthalmic lens.

Hybrid epoxy-acrylic with zirconium oxide nanocomposite for curable coatings

The present invention pertains to a method for producing a colloidal suspension of zirconia particles, including successively subjecting a mixture of zirconium oxychloride and an alkali metal halide in an aqueous solvent to hydrothermal treatment at a temperature above 150&#xb0; C, separating the slurry obtained from the supernatant, and peptizing said slurry by adding a strong acid thereto, and desalting said slurry, for example by ultrafiltration, so as to form a colloidal suspension of zirconia. The present invention also pertains to the transparent colloidal suspension obtainable by this method, and to an optical article, such as an ophthalmic lens, comprising a transparent polymer substrate and at least one coating prepared from a composition comprising said colloidal suspension.
