Title:
BI-LAYER ADHESIVE FOR LENS LAMINATION
Document Type and Number:
WIPO Patent Application WO/2010/053862
Kind Code:
A8
Abstract:
A method for laminating a film on to an optical article and a bi-layer adhesive for use in the method. The bi-layer adhesive includes a latex adhesive layer or a specific silane adhesive and an HMA layer sequentially disposed on the film and dried to form a solid layer of uniform thinness throughout to provide optical quality. Various types of films may be employed to provide an optical function. Following optional pre-treatment steps, the adhesives are coated on to the film. An optical hot press technique is used to deliver heat and pressure over a short period of time to form a functionally-enhanced optical article with high adhesive strength.
