Abstract: front page image
(EN)Disclosed is a method for producing a polarizing plate with an optical compensation layer wherein the optical compensation layer is not deteriorated and adhesion between a polarizer protection film and a polarizer is excellent. Specifically disclosed is a method for producing a polarizing plate with an optical compensation layer, which method comprises a step for arranging an optical compensation layer on one side of a polarizer protection film via a photocurable adhesive layer, a step for irradiating the other side of the polarizer protection film with ultraviolet light by using a metal halide lamp or a ultra high pressure mercury vapor lamp, and a step for arranging a polarizer on the side of the polarizer protection film where the optical compensation layer is not formed.
(FR)L'invention concerne un procédé de fabrication d'une plaque polarisante dotée d'une couche de compensation optique, empêchant la détérioration de la couche de compensation optique et assurant une excellente adhérence entre un film de protection de polariseur et un polariseur. Le procédé comprend les étapes consistant à appliquer une couche de compensation optique d'un côté d'un film de protection de polariseur au moyen d'une couche d'adhésif photodurcissable, à projeter une lumière ultraviolette sur l'autre côté du film de protection de polariseur au moyen d'une lampe à halogénures métalliques ou d'une lampe à vapeur de mercure ultra-haute pression, et à disposer un polariseur du côté du film de protection de polariseur dépourvu de la couche de compensation optique.
(JA) 光学補償層を劣化させず、かつ、偏光子保護フィルムと偏光子との密着性に優れる光学補償層付偏光板の製造方法を提供すること。  本発明の光学補償層付偏光板の製造方法は、偏光子保護フィルムの一方の側に光硬化型接着剤層を介して光学補償層を積層する工程と、該偏光子保護フィルムの他方の側からメタルハライドランプまたは超高圧水銀灯で紫外線を照射する工程と、該偏光子保護フィルムの該光学補償層が形成されない側に偏光子を積層する工程とを含む。
