Abstract

PURPOSE:To improve the degree of polarization, optical uniformity, heat resistance, moisture resistance, etc. by obtaining a high polymer film having optical dichroism by rolling alone or combination thereof with tensile stretching. CONSTITUTION:A blue dye having optical dichroism, polyester blue TGSF conc., is added at 0.1wt% to a polyethylene terephthalate resin having 0.70 intrinsic viscosity and 74 deg.C glass transition point Tg to form an unstretched raw sheet of a polarizing film. Such sheet is rolled about 5 times with a pair of rolling rolls. Said film is passed through rolling rolls and is then taken off in tight contact with the rolling roll operating at a high peripheral speed and further the film is heat-set by a far IR heater provided with a reflecting plate in such a way that the heat rays are converged to, for example, 5cm width. As a result, the polarizing film having excellent characteristics as shown in the table is obtd.
