異方性色素膜形成用組成物、異方性色素膜、および光学素子
Document Type and Number:
Japanese Patent JP7363887
Kind Code:
B2
Abstract:
The present invention provides a composition for forming an anisotropic dye film which enables the achievement of excellent optical performance, especially a sufficient dichroic ratio. A composition for forming an anisotropic dye film according to the present invention contains a dye and a polymerizable liquid crystal compound; and the dye contains a compound that is represented by formula (1). (1): A1-CH=CH-A2-(N=N-A3)n-X (In the formula, A1 represents a monovalent group of an aromatic hydrocarbon ring, which may have a substituent (excluding a sulfo group) or a monovalent group of an aromatic heterocyclic ring, which may have a substituent (excluding a sulfo group); each of A2 and A3 independently represents a divalent group of an aromatic hydrocarbon ring, which may have a substituent (excluding a sulfo group) or a divalent group of an aromatic heterocyclic ring, which may have a substituent (excluding a sulfo group); X represents a monovalent organic group; and n represents 1, 2 or 3.)
