Abstract:
The present invention relates to an optical article comprising on one of the main surfaces thereof an external water- and/or oil-repellent coating, characterized in that a temporary coat of a dried polyurethane latex-based composition is directly deposited onto the external water- and/or oil-repellent coating.
Abstract:
The optical article of the invention comprises on at least one of its main surfaces an outer hydrophobic and/or oleophobic coating and in direct contact with the outer hydrophobic and/or oleophobic coating a dual-layer temporary coating, characterized in that the dual-layer temporary coating comprises a first layer, in direct contact with the outer hydrophobic and/or oleophobic coating selected from halogenated olefin polymers and polyurethanes, and a second layer, deposited on the first layer, of a polymer or polymer mixture acting as a water barrier.Applies to ophthalmic lens edging.
Abstract:
The invention relates to a composition comprising one or more polymerizable monomers, comprising at least one masking agent selected amongst cyclic ethers and at least one perfume selected amongst naturally occurring musks and extracts thereof, synthetic musks, and mixtures thereof.
Abstract:
A method for manufacturing an ophthalmic lens includes molding the lens (1) between a first mold portion (6A) and a second mold portion (6B) with the first entry surface (4A) formed by making in the lens a molded cavity by means of a stud (6C) secured to the second mold portion (6B), and that the light guide (4) is temporarily secured to the stud (6C) prior to molding. The second entry surface (4B) is formed by making in the lens a molded cavity by means of a mold insert (7) temporarily secured to the light guide (4) prior to molding, the first mold portion (6A) being placed above said insert (7).
Abstract:
The present invention relates to a method for treating an optical lens coated on at least one of the main surfaces thereof with a hydrophobic and/or oleophobic external coating, to make it capable of undergoing an edging process, comprising a step of depositing onto at least one part of the hydrophobic and/or oleophobic external coating a temporary adhesive composite film, said adhesive composite film comprising a pre-formed film, one main surface of which is coated with a pressure-sensitive adhesive layer, said adhesive layer directly contacting the hydrophobic and/or oleophobic coating, the pre-formed film modulus of elasticity in tension E′ being higher than or equal to 4200 MPa, and the rupture stress of the assembly composed of said adhesive film bonded to a polycarbonate specimen coated with a fluorinated silane layer, measured under tensile stress in accordance with the shear strength evaluation standard NF EN 1465, being higher than or equal to 0.05 MPa.The present invention further relates to an edging method and to a lens capable of undergoing a successful edging process.

Abstract:
The invention relates to a method for treating an optical lens coated onto at least one of the main surfaces thereof with an outer hydrophobic and/or oleophobic coating, and for making it capable of undergoing an edging process, comprising a step of treating the peripheral area of said coated main surface which results in the removal of the hydrophobic and/or oleophobic coating and/or in the modification of said coating that lowers the hydrophobic character thereof, and a step of depositing a temporary polymeric coating onto said main surface of the lens so as to cover at least partially the hydrophobic and/or oleophobic coating and the peripheral area treated during the previous step, in order to provide an optical lens having onto at least one of the main surfaces thereof an outer hydrophobic and/or oleophobic coating and, in direct contact with said hydrophobic and/or oleophobic coating, a temporary polymeric coating adhering to the surface of the coated lens. The invention also relates to an edging method and to a lens capable of undergoing an edging process.
