Title:
DICHROIC DYE COMPOUND, DICHROIC DYE COMPOSITION, LIGHT-ABSORBING ANISOTROPIC FILM, POLARIZING ELEMENT, AND IMAGE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/090668
Kind Code:
A1
Abstract:
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.
