Abstract: front page image
(EN)Disclosed is a dye composition for anisotropic dye films which enables to form an anisotropic dye film having good heat resistance and few defects and exhibiting strong dichroism. Also disclosed are an anisotropic dye film formed by using such a dye composition and a polarizer employing such an anisotropic dye film. Specifically disclosed is a dye composition for anisotropic dye films containing a dye and a compound having two or more groups which are selected from the group consisting of acidic groups, basic groups and neutral groups and include at least one basic group. Also disclosed are an anisotropic dye film formed by using this dye composition and a polarizer employing such an anisotropic dye film.
(FR)L'invention concerne une composition de colorant pour des films colorés anisotropes qui permet de former un film coloré anisotrope présentant une bonne résistance à la chaleur, peu de défauts et fort dichroïque. L'invention concerne également un film coloré anisotrope obtenu au moyen de ladite composition de colorant et un polariseur utilisant ledit film coloré anisotrope. L'invention concerne en particulier une composition de colorant pour des films colorés anisotropes contenant un colorant et un composé qui possède au moins deux groupes sélectionnés à partir du groupe comprenant groupes acides, groupes basiques et groupes neutres et au moins un groupe basique. L'invention concerne également un film coloré anisotrope obtenu au moyen de ladite composition de colorant et un polariseur utilisant ledit film coloré anisotrope.
(JA)耐熱性が良好で、欠陥の少ない、高い二色性を示す異方性色素膜を形成することができる異方性色素膜用色素組成物と、この異方性色素膜用色素組成物を用いて形成された異方性色素膜と、この異方性色素膜を用いた偏光素子を提供する。 色素と、酸性基、塩基性基及び中性基よりなる群から選ばれる基を2つ以上有し、該2つ以上の基のうちの少なくとも1つは塩基性基である化合物とを含有する、異方性色素膜用色素組成物。この異方性色素膜用色素組成物を用いて形成された異方性色素膜。この異方性色素膜を用いた偏光素子。
