The bi-layer adhesive includes a latex adhesive layer 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 bi-layer adhesive is coated on to the film.
