摘要： An anisotropic dye film having high dichromatic properties is provided. An anisotropic dye film wherein the period d attributable to molecular stacking is at most 3.445 Å, and the column length L thereof is at least 105 Å. The anisotropic dye film preferably has a degree of orientation of the molecular stacking axes of at least 85% and a film thickness of at most 30 μm, and is formed by a wet film-forming method. Since it has a molecular alignment suitable to develop a dichroic ratio, it provides high dichromatic properties. A polarizing element having this anisotropic dye film is excellent in heat resistance, light fastness and polarizing performance.

摘要： An anisotropic dye film that exhibits a high dichroism and a high uniformity in a coating film is formed at a high level of productivity. In the composition for an anisotropic dye film containing a dye and being capable of forming a lyotropic liquid crystal phase, the time until the relaxation modulus G measured 0.01 seconds after the application of strain drops to 1/10 is equal to or shorter than 0.1 seconds at a temperature of 5° C. The composition contains a cation and a strongly acidic anion that respectively account for contents in the range of 0.9 to 0.99 equivalence and in the range of 0.02 to 0.1 equivalence relative to the content of the acidic groups of the dye. An anisotropic dye film is formed using this composition for an anisotropic dye film. A polarizing element is formed using this anisotropic dye film.
