SURFACE-MODIFYING METHOD OF A POLARIZER PROTECTION FILM CAPABLE OF IMPROVING SAPONIFICATION EFFICIENCY WITHOUT INCREASING THE TEMPERATURE OR CONCENTRATION OF ALKALI SOLUTION OR IMPREGNATION TIME

摘要

PURPOSE: A surface-modifying method of a polarizer protection film is provided to increase saponification efficiency while minimizing problems generated by alkali solution at saponification.;CONSTITUTION: A surface-modifying method of a polarizer comprises: a step of drying a polarizer protection film; and a step of saponifying alkali solution by a dried polarizer protection film. The polarizer protection film is formed of a diacetylcellulose resin, triacetylcellulose resin or a mixed resin thereof. On one side of the polarizer protection film, a coating layer or film with antireflective, antifouling, retardation, hardcoating or antistatic function is formed and laminated.;COPYRIGHT KIPO 2013
