Abstract
The present invention relates to a composition for forming a dye-type polarizer, which can be used to provide a dye-type polarizer showing excellent degree of polarization, heat resistance and dichroic ratio, and to a dye-type polarizer. The composition for forming a dye-type polarizer includes a curable anisotropic dye having a particular chemical structure; and an orientation auxiliary agent having a predetermined chemical structure.
