Patent number: 6149750Abstract: A conformable tape for bonding a lens block to ophthalmic lens blanks is provided. The tape comprises a polymeric backing and a pressure-sensitive adhesive. In a first preferred embodiment the surface of the backing is a blend of an olefin polymer with a polymer having acidic functionality. The blend may be formed as the backing layer, i.e., directly on the adhesive layer of the tape, or as the outer surface layer of a multilayered backing. In a second embodiment, the surface of the backing is a copolymer of an olefin monomer with a monomer having pendant acidic functionality. A lens block may be adhered to an ophthalmic lens blank by applying a section of the tape described above to an ophthalmic lens so that the pressure sensitive adhesive of the tape contacts the lens; conforming the tape to the compound surface of the lens; and attaching a lens block to at least a portion of the polymer backing layer.Type: GrantFiled: November 17, 1995Date of Patent: November 21, 2000Assignee: 3M Innovative Properties CompanyInventors: William L.
