Abstract
PURPOSE: To improve the water distribution property, the damp-proof property, and dimension stability of a obtained polarization plate, by using an adhesive material to cause the saponified face of a cellulose acetate film to adhere to the polarization film face.
CONSTITUTION: The processing aqueous solution of an alkali metal hydroxide is used to process one or both faces of the cellulose acetate film, and it is so saponified that the contant angle for water may be 30° or less approximately. A hydrophilic adhesive material is used desirably to cause the saponified face of the cellulose acetate film to adhere to one or both faces of the polarization film. the polarization plate obtained in this manner is superior in water-proof property, damp-proof property, and dimension stability and has a good polarization characteristic.
