METHOD FOR MANUFACTURING POLARIZING FILM

摘要

Provided herein is a method for producing a nano polaroid film using a one-pack type or two-pack type blackening ink so that a single layer film may replace a conventional polaroid film generally produced by superposing various types of optical films, and especially, a method for producing a nano polaroid film consisting of one film and having excellent observability by coating a transparent nano pattern substrate with a functional ink that contains a blackening material, and then removing particles formed on protruding portions using an etching solution, and refilling the functional ink into grooves.

主权项

1. A method for producing a polaroid film, comprising:
a first filling step of filling a blackening conductive ink composition into grooves of a substrate; and a second filling step of dissolving a residue blackening conductive ink composition that remains on a surface of the substrate after being filled into the grooves at the first filling step by an etching solution so that the residue blackening conductive ink composition is refilled into the grooves.
