Disclosed are a new dichroic dye having liquid crystal properties and dichroic properties and capable of being used for forming a polarization film with excellent heat resistance, durability, and polarizing properties, a composition including the same for a polarization film, a method for forming a polarization plate with excellent durability using the composition, and a polarization plate prepared thereby. The new dichroic dye has a structure of R1-L1-(M,L,D) (where, D is a dichroic structure, M is a structure with liquid crystal properties, R1 is a reactive end functional group, and L and L1 are linking structures). The composition for a polarization film includes the dichroic dye. In the method for forming the polarization plate, the composition for a polarization film is applied to a substrate and cured to prepare the polarization plate. The polarization plate has excellent dichroic ratio, heat resistance, durability, and polarizing properties.
本发明公开了一种新的具有液晶性能和双折射性能的二色染料,可用于形成具有优异耐热性、耐久性和偏振性能的偏振膜的组合物,以及使用该组合物制备具有优异耐久性的偏振板的方法和所制备的偏振板。新的二色染料具有R1-L1-(M,L,D)的结构(其中,D是双折射结构,M是具有液晶性能的结构,R1是反应性末端功能团,L和L1是连接结构)。偏振膜的组合物包括该二色染料。在制备偏振板的方法中,将偏振膜的组合物涂覆在基板上并固化以制备偏振板。该偏振板具有优异的双折射比、耐热性、耐久性和偏振性能。
