    Abstract: A process for applying a coated or uncoated film onto at least one surface of a lens substrate which comprises the steps of : (a) providing a lens substrate (1) having main surfaces ; (b) providing a coated or uncoated film (3,4); (c) forming, on either a surface of the coated or uncoated film or one of the said surfaces of the lens substrate, a layer of a dry latex (5); (d) depositing at least one drop of a water base activating liquid (6) on either the said main surface (2) of the lens substrate, a surface of the coated or uncoated film or an exposed surface of the dry latex layer (5); (e) moving relatively to each other the coated or uncoated film and the lens substrate and applying a sufficient force to the coated or uncoated film to spread the water base activating liquid and form a thin pellicule thereof between the dry latex layer (5) and either the lens substrate or the coated or uncoated film (3,4); (f) heating the thin pellicule of water base activating liquid and the dry latex layer (5); (g) releasing the applied force; and (h) recovering the lens substrate (1) with the coated or uncoated film (3,4) adhered to the lens substrate main surface.

    Abstract: The invention concerns a photocurable adhesive composition comprising, based on total weight of photopolymerizable monomers and/or oligomers of the composition: 5 to 60 wt % of at least one mono or polyacrylate monomer or oligomer thereof (A); 5 to 50 wt % of at least one thio(meth)acrylate monomer or oligomer thereof (B); and 20 to 50 wt % of at least one aromatic dimethacrylate monomer or oligomer thereof (C); with the proviso that the composition does not contain a brominated monofunctional acrylate.

    Abstract: A process for transferring a coating onto at least one optical surface of a lens blank which comprises : providing a lens blank having at least one geometrically defined surface ; providing a support having an internal surface bearing a coating and an external surface ; depositing on said geometrically defined surface of said lens blank or said coating a pre-measured amount of a curable glue ; moving relatively to each other the lens blank and the support to either bring the coating into contact with the curable glue or bring the curable glue into contact with the geometrically defined surface of the lens blank ; applying a sufficient pressure onto the external surface of the support so that the thickness of a final glue layer after curing is less than 100 micrometers ; curing the glue ; and withdrawing the mold part to recover the lens blank with the coating adhered onto its geometrically defined surface.
