COMPOSITION FOR ANISOTROPIC DYE FILM AND ANISOTROPIC DYE FILM

摘要

The present invention addresses the problem of providing a composition for an anisotropic dye film that has excellent optical characteristics and is suitable for a process for producing displays, and an anisotropic dye film. The composition according to the present invention for an anisotropic dye film contains azo dyes and a solvent wherein the azo dyes comprise an azo dye that is represented by formula (I) in the form of a free acid and an azo dye that is represented by formula (III) in the form of a free acid. Ar11-N=N-Ar12-N=N-Ar13-N=N-Ar14 (I) Ar21-N=N-Ar22-N=N-Ar23 (III)
