MANUFACTURING METHOD OF POLARIZING PLATE PROTECTIVE FILM, POLARIZING PLATE PROTECTIVE FILM AND POLARIZING PLATE INCLUDING THE SAME, LIQUID CRYSTAL DISPLAY DEVICE, AND MANUFACTURING METHOD OF OPTICAL FILM

摘要

PROBLEM TO BE SOLVED: To provide a polarizing plate protective film having low moisture permeability and excellent hardness and a manufacturing method of the same, and to provide a polarizing plate that is hardly deteriorated by absorption of moisture and a liquid crystal display device.;SOLUTION: There is provided a manufacturing method of a polarizing plate protective film 110 having a cellulose ester base material 111 and a hard coat layer 112 formed on at least one surface 111s of the cellulose ester base material 111, the method including: forming, on the surface 111s, a coating film 112a by applying a photo-curable composition including a monomer component including vinyl cyclohexene dioxide, a photo cation polymerization initiator, and an organic solvent in an amount of 0 to 10 mass%; and irradiating the coating film 112a with an ultraviolet ray to polymerize at least vinyl cyclohexene dioxide.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2016,JPO&INPIT
