摘要： A polarizing film which includes a substrate resin and a dichromic substance features: (1) the uniaxial orientation coefficient f of the crystal principal axis of the film with respect to the reference axis is 0.7 or more; and the product (f x R), which is between the uniaxial orientation coefficient f and the ratio R (R=(Imin/Imax) x 100) between the maximum value (Imax) and the minimum value (Imin) of the X-ray diffraction intensities on the Debye-Scherrer ring which are measured when X-rays are applied to the surface orthogonal to the reference axis in parallel to the reference axis, is 10 or more. Also disclosed is a method of manufacturing the polarizing film. This polarizing film has excellent heat-resistant and moisture-resistant properties and a high degree of polarization.

摘要： Polarizing film with excellent humidity and heat resistances, which is substantially insoluble in water, organic solvents, and liquid crystals and which comprises a hydrophobic polymer containing in an oriented state a dichroic organic dye having a dichroic ratio of 7 or more measured as a film formed by uniformly mixing the dye with polyethylene terephthalate and melt-forming the mixture into film.
