Title:
防汚皮膜を備えた光学レンズをエッジングの前に粘着フィルムを用いて処理する方法
Document Type and Number:
Japanese Patent JP5616903
Kind Code:
B2
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.
