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.
提供具有高二色性能的各向异性染料膜。其中,由分子堆积引起的周期d最多为3.445 Å,其柱长L至少为105 Å。该各向异性染料膜最好具有分子堆积轴的取向度至少为85%,膜厚最多为30 µm,并且是通过湿膜成型方法形成的。由于具有适合发展二色比的分子排列,它提供了高二色性能。具有这种各向异性染料膜的偏振元件在耐热性、耐光性和偏振性能方面表现出色。
