Title (EN) POLARIZING ARTICLE AND METHOD OF FORMING A POLARIZING ARTICLE
(FR) ARTICLE POLARISANT ET PROCÉDÉ DE FORMATION D'UN ARTICLE POLARISANT
Abstract:
(EN) The present invention relates to a polarizing article that includes in order: (a) a substrate; (b) a first orientation facility having a first orientation direction; (c) a first polarized layer, that includes a first dichroic fixed-tint dye and a first liquid-crystal material, and which has a first polarization axis; (d) a second orientation facility having a second orientation direction; and (e) a second polarized layer that includes a second dichroic fixed-tint dye and a second liquid-crystal material, and which has a second polarization axis. The first and second polarization axes are oriented relative to each other at an angle of greater than 0° and less than or equal to 90°. The electromagnetic absorption spectra of the first and second dichroic fixed-tint dyes are different from each other.
(FR) La présente invention concerne un article polarisant comprenant, dans l'ordre : (a) un substrat ; (b) une première installation d'orientation ayant une première direction d'orientation ; (c) une première couche polarisée, comprenant un premier colorant dichroïque à teinte fixe et un premier matériau à cristaux liquides, et ayant premier axe de polarisation ; (d) une seconde installation d'orientation ayant une seconde direction d'orientation ; et (e) une seconde couche polarisée comprenant un second colorant dichroïque à teinte fixe et un second matériau à cristaux liquides, et ayant un second axe de polarisation. Les premier et second axes de polarisation sont orientés l'un par rapport à l'autre selon un angle supérieur à 0° et inférieur ou égal à 90 °. Les spectres d'absorption électromagnétique des premier et second colorants à teinte fixe dichroïque sont différents l'un de l'autre.
