发明名称 偏光性積層フィルムの製造方法及び偏光板の製造方法
摘要 A method for manufacturing a polarizing laminated film and a method for manufacturing a polarizing plate using a polarizing laminated film obtained thereby. This method for manufacturing a polarizing laminated film has the following steps: a step in which a laminated film provided with a first resin layer on one surface of a base film and a second resin layer on the other surface of said base film is obtained via the application of a coating liquid containing a polyvinyl-alcohol resin; a step in which said laminated film is stretched, yielding a stretched film; a step in which said stretched film is conveyed while being supported by guide rollers and is wound around a shaft in a take-up part; and a step in which a dichroic pigment is used to dye the first and second resin layers on the stretched film so as to form polarizer layers, yielding a polarizing laminated film. The stretched film is wound with a distance of no more than 600 mm between the axis of the take-up part and the axis of the guide roller closest to the take-up part.
