Abstract

See full text

A method for laminating a functional film on to an optical base element and a tri-layer adhesive system for use in the method. The tri-layer adhesive includes a first latex adhesive layer disposed on the functional film and a second latex adhesive layer disposed on the optical base element. An HMA layer is disposed in between the latex layers to form a tri-layer adhesive to permanently retain the functionalized film on the optical base element. The method includes first coating a latex adhesive on the functional film and second coating a latex adhesive on the optical base element. An HMA is then coated on to one of the dried latex adhesive layers. The film is hot pressed on to the optical base element with the HMA sandwiched in between the latex layers to form a laminated optical device.
