PCT No. PCT/JP86/00091 Sec. 371 Date Sep. 8, 1986 Sec. 102(e) Date Sep. 8, 1986 PCT Filed Feb. 25, 1986 PCT Pub. No. WO86/04998 PCT Pub. Date Aug. 28, 1986.The present invention relates to a high-performance light-polarizing film assuming a neutral gray wherein are absorbed and oriented, in a polymer film, (A) iodine as a main polarizing coloring matter and additionally (B) a dichroism dye having a absorption characteristics and polarization characteristics in the low wavelength region of visible light and showing, when absorbed and oriented together with iodine in a polymer film, a direction of transition moment substantially identical with that of iodine and/or a dichroism dye having absorption characteristics and polarization characteristics in the high wavelength region of visible light and showing, when absorbed and oriented together with iodine in a polymer film, a direction of transition moment substantially identical with that of iodine. As compared with the prior iodine type light-polarizing films, the light-polarizing film obtained in the above-mentioned manner has a high light transmittance in the wavelength range of visible light, assumes a neutral gray and has a high polarizing co-efficient. Accordingly, it is effectively usable as a liquid crystal material for liquid crystal television and the like and effectively applicable to optical uses such as CRT filter and the like.
