A color polarizer with a support whose brightness and polarization performance are good for a blue channel (for blue light). The color polarizer for a liquid crystal projector including a support and a color polarizer which contains stilbene water-soluble azoic dye as dichroic molecule and has a single plate average transmittance of more than 39 % in a range from 420 to 500 nm, an average transmittance of less than 0.4 % at the orthogonal position, and an average transmittance of more than 4 % at the orthogonal position in a range from 650 to 780 nm.
L'invention porte sur un polariseur de couleur pour projecteur à cristaux liquides muni d'un support, dont la brillance et les qualités de polarisation sont bonnes pour un canal bleu (pour la lumière bleue). Ledit polariseur, qui contient comme molécule dichroïque un colorant azoïque hydrosoluble de stilbène, présente une transmittance moyenne sur plaque unique de plus de 39 % entre 420 et 500 nm, une transmittance moyenne de moins de 0,4 % en position orthogonale, et une transmittance moyenne de moins de 4 % en position orthogonale entre 650 et 780 nm.
