METHOD FOR PRODUCING LAMINATE FILM, METHOD FOR PRODUCING POLARIZING LAMINATE FILM, AND METHOD FOR PRODUCING POLARIZING PLATE
Document Type and Number:
WIPO Patent Application WO/2011/125957
Kind Code:
A1
Abstract:
Disclosed are a method for producing a laminate film, a method for producing a polarizing laminate film using said laminate film, and a method for producing a polarizing plate using said polarizing laminate film, which have a resin layer forming step (S10) comprising: an application step wherein a solution containing a polyvinyl alcohol resin is applied to one surface of a base film, forming an applied resin layer; and a drying step wherein the abovementioned applied resin layer is dried, forming a resin layer; and in the abovementioned application step, an un-applied portion is provided to which the abovementioned solution is not applied in the region at least 0.5 cm inwards from each edge in the widthwise direction of the abovementioned base film. By means of the present disclosures, provided is a method for producing a polarizing plate in a manner that prevents a bending phenomenon and that has good production characteristics.
