| 摘要 |
The invention relates to a method for treating an optical lens coated on at least one of its main surfaces by an external hydrophobic and/or oleophobic coating, in order to render it suitable for edging. Said method comprises a step for the deposition, on at least one part of the external hydrophobic and/or oleophobic coating, of a temporary adhesive composite film, said adhesive composite film comprising a pre-shaped film, the main surface of which is coated with a pressure-sensitive adhesive layer, the adhesive layer being in direct contact with the hydrophobic and/or oleophobic coating, the elasticity during traction E' module of the pre-shaped film being higher than, or equal to, 4200 MPa, and the tensile strength of the assembly consisting of said adhesive film stuck to a sample of polycarbonate coated with a layer of fluorinated silane, measured during traction in conformance with the norm of determination of shear strength NF EN 1465, being higher than, or equal to, 0.05 MPa. The invention also relates to an edging method and to a lens suitable for edging. |
