<p>Anti-abrasive film comprises a transparent thermoplastic polymer film, and an anti-abrasive coating composite covering the film. The anti-abrasive coating composite includes: a lower layer that is disposed on the transparent thermoplastic polymer film and is obtained by hydrolysis and then curing a lower layer composition comprising at least one epoxysilane and at least one alkoxysilane; and an upper layer that is disposed on the lower layer and is obtained by hydrolysis and then curing an upper layer composition comprising at least one epoxysilane and at least one alkoxysilane. Anti-abrasive film comprises a transparent thermoplastic polymer film, and an anti-abrasive coating composite covering the film. The anti-abrasive coating composite includes: a lower layer that is disposed on the transparent thermoplastic polymer film and is obtained by hydrolysis and then curing a lower layer composition comprising at least one epoxysilane and at least one alkoxysilane in a weight ratio (Ri) of, as a dry material, at least 3; and an upper layer that is disposed on the lower layer and is obtained by hydrolysis and then curing an upper layer composition comprising at least one epoxysilane and at least one alkoxysilane in a weight ratio (Rs) of, as a dry material, at least 2. Independent claims are included for: (1) an optical article, preferably ophthalmic lens comprising an organic glass transparent substrate, an adhesive layer covering the sides of the substrate, and an anti-abrasive film; and (2) fabricating an optical article comprising either disposing the organic glass transparent substrate, providing the anti-abrasive film, contacting the adhesive layer with the transparent substrate and applying an uniform pressure over the entire contact area so as to bond the anti-abrasive film on the organic substrate, or disposing the organic glass transparent substrate, preferably ophthalmic lens coated on at least one side of the adhesive layer, providing the anti-abrasive film, contacting the side of anti-abrasive film bearing the transparent film with the adhesive layer and applying an uniform pressure over the entire contact area so as to bond the anti-abrasive film on the organic substrate.</p> |
