Abstract

L'invention concerne un film polarisant pourvu : d'un polariseur ; d'une première couche décorative et d'une première couche adhésive, qui sont disposées sur un côté surface principale du polariseur ; et d'une seconde couche décorative ainsi que d'une seconde couche adhésive ou d'un film protecteur, qui sont disposés sur l'autre côté surface principale du polariseur. La première couche décorative est directement liée à la partie périphérique de la première surface principale sans couche de liaison interposée entre celles-ci ; et la première couche adhésive recouvre une surface de la première couche décorative, ladite surface étant sur le côté inverse du polariseur, et des régions de ladite surface principale auxdites régions de la première couche décorative n'étant pas liées. La seconde couche décorative est directement liée à la partie périphérique de l'autre surface principale sans couche de liaison interposée entre celles-ci ; et la seconde couche adhésive recouvre une surface de la seconde couche décorative, ladite surface étant sur le côté inverse du polariseur, et des régions de l'autre surface principale auxdites régions de la seconde couche décorative n'étant pas liées. Le film protecteur est directement lié à l'autre surface principale sans couche adhésive interposée entre eux ; ou en variante, le film protecteur est lié à l'autre surface principale avec une couche de liaison interposée entre eux. La première couche décorative, la seconde couche décorative et le film protecteur ont un taux de transmission de vapeur d'eau inférieur ou égal à 1 500 g/m2·24 h à une épaisseur de 25 µm.
