DICHROIC DYE-CONTAINING LIQUID, AND POLARIZER

摘要

To provide a dichroic dye-containing liquid that is capable of preventing haze without decrease of adhesiveness of a polarizing layer, and a polarizer. The dichroic dye-containing liquid contains (A) a dichroic dye and (B) a toughness-imparting agent, in which the dichroic dye (A) and the toughness-imparting agent (B) are dispersed or dissolved in an aqueous medium, and a solid content X (% by mass) of the toughness-imparting agent (B) based on the dichroic dye-containing liquid and a 100% modulus Y (MPa) of the toughness-imparting agent (B) satisfy relationships represented by the following expressions (1) and (2):
and the polarizer contains a substrate having provided sequentially thereon an orientation layer and a polarizing layer, in which the polarizing layer containing a dichroic dye that is oriented and accumulated by using the dichroic dye-containing liquid.
