摘要:
The ophthalmic lens according to the invention comprises a substrate made of organic glass, having front and rear main faces, at least one primer layer deposited on at least one of the main faces of the substrate, the said primer layer comprising an aggregate of at least two-phase particles, a first phase of which consists of a polymer P1 with a soft character having a glass transition temperature (Tg) of less than 20° C. and a second phase of which consists of a polymer P2 with a hard character having a glass transition temperature (Tg) of greater than 50° C., and at least one layer of an abrasion-resistant coating composition deposited on the primer layer. Application to lenses for spectacles.
