Title (EN) MULTI-LAYER FILM DEPICTING A COLOUR TWO-DIMENSIONAL IMAGE WHICH IS ONLY VISIBLE THROUGH A POLARIZING FILTER AND PROCESS FOR MAKING THE FILM
(FR) FILM MULTICOUCHE PRÉSENTANT UNE IMAGE BIDIMENSIONNELLE EN COULEURS SEULEMENT VISIBLE À TRAVERS UN FILTRE DE POLARISATION ET PROCÉDÉ DE FABRICATION DU FILM
Abstract:
(EN) A film (1) depicting a colour two-dimensional image which is only visible through a polarizing filter comprises an optically active layer (2) placed over a polarizing layer (3) and configured to form said image on its face opposite the polarizing layer (3) when said face is seen through the polarizing filter; the optically active layer comprises a plurality of areas (4) arranged side by side in said face to form corresponding portions of the image, each area (4) being mechanically stressed to a predetermined intensity so that the corresponding portion of the image has a predetermined colour when seen through the polarizing filter. Also described is an apparatus (6) for making the film (1).
(FR) L'invention concerne un film (1) présentant une image bidimensionnelle en couleurs seulement visible à travers un filtre de polarisation, le film comprenant une couche optiquement active (2) placée au-dessus d'une couche de polarisation (3) et configurée pour former ladite image sur sa face opposée à la couche de polarisation (3) quand ladite face est vue à travers le filtre de polarisation. La couche active optiquement comprend une pluralité de zones (4) agencées côte à côte dans ladite face pour former des parties correspondantes de l'image, chaque zone (4) étant contrainte mécaniquement à une intensité prédéterminée, de telle sorte que la partie correspondante de l'image ait une couleur prédéterminée quand elle est vue à travers le filtre de polarisation. L'invention concerne également un appareil (6) pour fabriquer le film (1).
