<p>Optical article comprising a transparent substrate and an abrasion-resistant layer appended to the at least one surface of said substrate, wherein said abrasion-resistant layer results from the reaction mixture of the following compounds:
- a first organo-silane chosen from thiocarbamate-silane matrix precursor containing at least one terminal alkoxysilane group, or hydrolysates thereof,
- an inorganic oxide selected from the group consisting of silica, iron, titanium, cerium, zirconium, antimony, zinc, tin oxides, and composite oxides thereof,
- a curing catalyst for said thiocarbamate-silane, and
- a solvent for said organo-silane.
The invention also relates to a process for manufacturing said articles, and to the use of the above-mentioned article for the manufacturing of optic glasses or lenses.</p> |
