Title (EN) POLARIZATION PLATE MANUFACTURING METHOD
(FR) PROCÉDÉ DE FABRICATION DE PLAQUE DE POLARISATION
(JA) 偏光板の製造方法
Abstract:
(EN) A polarization plate manufacturing method is provided which involves: a step in which a latex layer is formed on a substrate and dried, producing on the substrate a transfer film on which an optical film is formed; a step in which a polarizer is bonded onto the optical film-side surface of the transfer film; and a step in which the substrate is separated from the transfer film. When the latex forming the latex layer is mixed at 10 wt% with cyclohexanone, then the surface energy is 41.0-48.0 mN/m on the side of the substrate where the latex forms the latex layer substantially without dissolving, and the thickness of the optical film is 1-10μm.
(FR) L'invention concerne un procédé de fabrication de plaque de polarisation qui met en œuvre : une étape dans laquelle une couche de latex est formée sur un substrat et séchée, ce qui produit sur le substrat un film de transfert sur lequel un film optique est formé ; une étape dans laquelle un polariseur est collé sur la surface côté film optique du film de transfert ; et une étape dans laquelle le substrat est séparé du film de transfert. Lorsque le latex formant la couche de latex est mélangé à 10 % en poids avec de la cyclohexanone, alors l'énergie de surface est de 41,0 à 48,0 mN/m du côté du substrat où le latex forme la couche de latex sensiblement sans dissolution, et l'épaisseur du film optique est de 1 à 10 µm.
(JA) 本発明により、基材上にラテックス層を形成し、乾燥することにより、上記基材上に光学フィルムを形成した転写フィルムを作成する工程、 上記転写フィルムの上記光学フィルム側表面に偏光子を貼り合わせる工程、 上記転写フィルムから上記基材を剥離する工程を有し、 上記ラテックス層を形成するラテックスが、シクロヘキサノンに10重量パーセントで混合された場合、実質的に溶解せず、 上記基材の上記ラテックス層を形成する側の表面エネルギーが、41.0~48.0mN/mであり、 上記光学フィルムの厚さが1~10μmである、偏光板の製造方法が提供される。
