SURFACE PROCESSING METHOD OF A POLARIZER PROTECTING FILM FOR INCREASING ADHESIVE STRENGTH, AND A POLARIZING PLATE USING THE SAME

摘要

PURPOSE: A surface processing method of a polarizer protecting film and a polarizing plate using the same are provided to achieve excellent adhesive strength and maintain the adhesive strength for a long time while maintaining optical properties at least equal to those of the existing methods when bonded to a polarizer.;CONSTITUTION: A surface processing method of a polarizer protecting film includes a step of applying plasma discharge treatment to one or both sides of a polarizer(4) protecting film by using reaction gas containing amino compounds having an unsaturated double bond in at least one terminus. A polarizing plate is formed by bonding a polarizer to the plasma discharge-treated side of the surface-processed polarizer protecting film.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Absorption side(stretching direction);
