Abstract

PURPOSE: To obtain the polarizer of a neutral grey color of superior moisture resistance and heat resistance and high durability by adsorbing (impregnating) the specific organic base direct dye on a hydrophilic macromolecular film as a polarizing element and orienting the same.
CONSTITUTION: For example, the organic base direct dye of 70% or less in the maximum transmittance in a visible region (700W400nm) in 0.1% aqueous solution and 30% or less in the difference between the maximum transmittance and minimum transmittance, expressed by formula I, formula II is used as a polarizing element. More specifically, a polyvinyl-alcohol-base-, saponified ethylene-vinyl acetate- copolymer-base- or cellulosic-base film, etc. is dipped in an aqueous solution of about 1W4% boric acid at about 30W40°C. After this is stretched 3W7 times, it is dipped in the aeqeous solution of the above-mentioned dye of about 0.05W0.5% at about 30W40°C to allow the dye to adsorb, thence it is dried and heat set at about 80W100°C, whereby the polarizer of a neutral grey color is obtained.
