Method for producing a polarizing plate

The present invention provides a method for producing a polarizing plate by laminating a polarizing film 1 including polyvinyl alcohol resin and a cycloolefin resin film 2 with laminating through adhesive to form a laminated body 4 while the polarizing film 1 and the cycloolefin resin film 2 are tra...

Zusammenfassung:	The present invention provides a method for producing a polarizing plate by laminating a polarizing film 1 including polyvinyl alcohol resin and a cycloolefin resin film 2 with laminating through adhesive to form a laminated body 4 while the polarizing film 1 and the cycloolefin resin film 2 are transported in the same direction, and then curing the adhesive for producing polarizing plate 5, in which the cycloolefin resin film 2, for example, is heat treated at temperature of 80 to 120 DEG C in a hot-air oven 10, and then laminated with the polarizing film 1 through the adhesive.
