Abstract:
(EN) The present invention addresses the problem of providing a dichroic dye compound that maintains a superior polarization level when used in a polarizing element and that has good solubility, a dichroic dye composition, a light-absorbing anisotropic film, a polarizing element, and an image display device. The dichroic dye compound according to the present invention is a dichroic dye compound that has a structure represented by formula (I). Here, in formula (I), each of L1 and L2 independently represents a divalent aliphatic hydrocarbon group that may include a substituent or a heteroatom, each of E1 and E2 independently represents -O(C=O)- or -(C=O)O-, G represents a branched monovalent aliphatic hydrocarbon group, each of n, m, p, q, and r independently represents 0 or 1, and the sum of m, q, and r is 2 or 3. However, when the sum of m and q is 2, G represents a linear or branched monovalent aliphatic hydrocarbon group.
(FR) La présente invention concerne un composé colorant dichroïque qui maintient un niveau de polarisation supérieur lorsqu'il est utilisé dans un élément polarisant et qui présente une bonne solubilité, une composition de colorant dichroïque, un film anisotrope absorbant la lumière, un élément polarisant et un dispositif d'affichage d'image. Le composé colorant dichroïque selon la présente invention est un composé colorant dichroïque qui possède une structure représentée par la formule (I). Dans la formule (I), L1 et L2 représentent chacun indépendamment un groupe hydrocarboné aliphatique divalent qui peut comprendre un substituant ou un hétéroatome, E1 et E2 représentent chacun indépendamment -O(C=O)- ou -(C=O)O-, G représente un groupe hydrocarboné aliphatique monovalent ramifié, n, m, p, q et r représentent chacun indépendamment 0 ou 1 et la somme de m, q et r est égale à 2 ou 3. Cependant, lorsque la somme de m et de q est égale à 2, G représente un groupe hydrocarboné aliphatique monovalent ramifié ou linéaire.
(JA) 本発明は、偏光素子に用いた際に優れた偏光度を維持し、溶解性が良好な2色性色素化合物、2色性色素組成物、光吸収異方性膜、偏光素子および画像表示装置を提供することを課題とする。本発明の2色性色素化合物は、式(I)で表される構造を有する2色性色素化合物である。 ここで、式(I)中、L1およびL2は、それぞれ独立に置換基またはヘテロ原子を有していてもよい2価の脂肪族炭化水素基を表し、E1およびE2は、それぞれ独立に-O(C=O)-または-(C=O)O-を表し、Gは、分岐鎖状の1価の脂肪族炭化水素基を表し、n、m、p、qおよびrは、それぞれ独立に、0または1を表し、かつ、m、qおよびrの合計が2または3を表す。ただし、mおよびqの合計が2である場合、Gは、直鎖状または分岐鎖状の1価の脂肪族炭化水素基を表す。
