    摘要： The present invention provides a method of manufacturing a polarizing plate having sufficient heat resistance, without deteriorating the dye-affinity and the like of the polarizing film and without the necessity of transferring or detaching the polarizing film. Provided is a method of manufacturing a polarizing plate (10) that includes a polyester resin base (11) and a polarizing film including a polyvinyl alcohol resin laminated on the polyester resin base. The method includes the steps of; stretching a laminate that includes a polyvinyl alcohol resin layer (12) laminated on the polyester resin base (11); dyeing the polyvinyl alcohol resin layer (12); and crystallizing the polyester resin base (11). The crystallization step is performed after the dyeing step.

    摘要： Provided is a polarizer protective film of thin type, which has excellent heat resistance and excellent transparency as well as excellent UV-absorbing ability, has good external appearance of a film surface, and can be stably produced by film forming. The polarizer protective film of the present invention includes a resin layer (A) and a resin layer (B1) in the stated order, in which the resin layer (A) is a resin layer containing a (meth) acrylic resin as a main component and contains a UV absorber at a ratio of 0.5 to 10 wt % with respect to a resin component contained in the resin layer (A), and the resin layer (B1) is a resin layer containing a (meth) acrylic resin as a main component and contains a UV absorber at a ratio of more than 0 wt % and 2 wt % or less with respect to a resin component contained in the resin layer (B1).
