Abstract

A functionalized layered structure (2, 3, 20, 30) includes: a first element that is a first single-layer or multi-layer functional film (2A, 4); at least one second element selected among a second functional film (2B) and a basic optical element (200, 300); at least one first pressure-sensitive adhesive layer (5A, 5B, 5) placed in contact with at least one surface of the first element and at least one surface of the second element. The surfaces of the first and second element, which are intended for being placed in contact with the adhesive layer, are subjected to a surface treatment prior to being placed in contact, such that the decrease between the peel force when dry and the peel force when wet is no higher than at least 35%, inclusive.
