光学膜卷绕体、其保管方法、以及基材膜/偏振片层叠体的制造方法
Abstract:
本发明涉及一种光学膜卷绕体、其保管方法、以及基材膜/偏振片层叠体的制造方法，上述光学膜卷绕体是将长度1000m以上的基材膜/遮蔽膜层叠体卷绕而成的长条的光学膜卷绕体，上述基材膜/遮蔽膜层叠体是使基材膜和遮蔽膜层叠而成的，上述遮蔽膜是由在25℃以上70℃以下具有熔融峰的材料形成的，上述基材膜与偏振片的剥离强度在卷中部分和卷外部分满足规定的关系。
Abstract(English):

Provided is a long optical film winding body obtained by winding a base film/masking film laminate of 1000 m or more formed from lamination of a base film and a masking film, wherein the masking film is formed from a material having a melting peak of 25-70 DEG C, and a winding part and a non-winding part of the optical film winding body satisfy a prescribed relationship for the peel strength of the base film and a polarizing plate. Also provided are a storage method for the same and a method for manufacturing a base film/polarizing plate laminate.
