Abstract: Disclosed are methods for preparing a laminate incorporable to a surface of an optical lens. A front surface and/or back surface of a photochromic film or a functional film is pre-treated. A second thermoplastic film is then laminated on each pre-treated surface of the photochromic film or functional film using a water-based adhesive. The pre-treatment applied on the surface(s) of the photochromic film or functional film enables the formation of strong adhesion between the second thermoplastic film and the water-based adhesive.

Abstract: A polarizing structure comprising a polarizing film, a protective film provided on at least one face of the polarizing film with an adhesive layer which is a glyoxal-based adhesive or a water based polymer adhesive such as a PVOH-based adhesive layer, and wherein at least one face of said protective film oriented towards said polarizing film further comprises an adhesion primer structure. The adhesive avoids delamination of the polarizing structure, which withstands edging processing conditions, and which also show excellent dry peel force. Other aspects of the invention relates to a method for manufacturing such a polarizing structure, and a polarized ophthalmic lens comprising such polarizing structure.
