PROBLEM TO BE SOLVED: To provide a dye that forms a good association state such as lyotropic liquid crystal in a solution. A dye for an anisotropic dye film represented by the following general formula (1): (In the formula, X represents a dye skeleton, n represents an integer of 2 or more, Y represents a direct bond, O, S, NH, NCH 3 , and Z may have a direct bond or a substituent. alkylene group having 1 to 10 carbon atoms, which may have an optionally substituted (where m represents an integer of 1~4) (-CH 2 CH 2 O- ) m group or a substituted group Represents a good (—CH 2 CH 2 O—) m ′ (—CH 2 —) m ″ group (where m ′ represents an integer of 1 to 4 and m ″ represents an integer of 1 to 4), Ar 1 and Ar 2 each independently represents an aromatic hydrocarbon group which may have a substituent or an aromatic heterocyclic group which may have a substituent, and a plurality of which are included in one molecule. Y, Z, Ar 1 and Ar 2 may be the same or different.) [Selection figure] None |
