Document Type and Number:
WIPO Patent Application WO/2020/174728
Kind Code:
A1
Abstract:
This method for producing a polarizing film involves providing a transparent protective film to at least one side of a polarizing element, with an adhesive layer interposed therebetween. The method for producing a polarizing film is characterized by having an application step in which the highly adhesive composition is applied to the side of the polarizing element on which the adhesive layer is to be formed, and the highly adhesive composition containing: a specific boron-containing compound; and one or both of an organic solvent having a boiling point of 85°C or higher and a monomer comprising a polymerizable group having a boiling point of 85°C or higher.
