Patent ID: 8435378

Claim:
A process for transferring at least one coating onto at least one geometrically defined surface of a lens substrate comprising: (a) obtaining a carrier having a main surface bearing at least one functional coating; (b) obtaining a lens substrate having at least one geometrically defined surface; (c) depositing, either on said at least one functional coating or said at least one geometrically defined surface of the lens substrate, a layer of a transparent adhesive composition; (d) bringing said layer of transparent adhesive composition to a pre-cured or hardened state by UV radiation or by drying the layer at a temperature ranging from 40° C. to 130° C. at which the layer becomes unflowable under the process conditions if said layer has not already been transferred in a dry form from a separable film supporting element at the end of step (c), such that the layer of transparent adhesive composition is no longer significantly spreadable; (e) moving the carrier and the lens substrate relatively to each other to bring the layer of transparent adhesive composition into direct contact with either said at least one geometrically defined surface of the lens substrate or said at least one functional coating; (f) pressing together the layer of transparent adhesive composition and either said at least one functional coating or said at least one geometrically defined surface of the lens substrate; (g) stopping pressing step (f); and (h) withdrawing the carrier to recover the lens substrate coated with said at least one functional coating adhering to said at least one geometrically defined surface through the layer of transparent adhesive composition, wherein step (d) is performed prior to steps (e) and (f).
