ABSTRACT:
Disclosed is a polarizing film comprising a hydrophobic polymer containing a dichroic organic colorant in an oriented state which is characterized in that the dichroic organic colorant is substantially insoluble in water, organic solvents and liquid crystals and the dichroic ratio of the colorant is not less than 7 when it is measured with the film obtained by blending the colorant intimately with polyethylene terephthalate, melting the resulting blend and forming it into a film. This polarizing film has exceptionally excellent moisture resistance and thermal resistance.
