Title:
METHOD FOR MANUFACTURING A POLARIZER
Document Type and Number:
WIPO Patent Application WO/2012/002662
Kind Code:
A2
Abstract:
The present invention relates to a method for manufacturing a polarizer, and more particularly, to a method for manufacturing a polarizer, comprising: a first cross-linking step using only an inorganic cross-linking agent such as a boron compound; and a second cross-linking step using an organic cross-linking agent which is a cyclic hypervalent carboxylic acid compound having two or more carboxyl groups, thereby effectively strengthening a cross-linking reaction, improving optical characteristics, and enabling the polarizer to have a large area and to be thin without causing fractures or wrinkles in a film under high draw-ratio conditions, and enabling the polarizer to have superior dimensional stability in both the vertical and horizontal directions, as well as color durability while being heat-resistant. The method of the present invention enables easy treatment during process and improves production efficiency.
