Abstract: front page image
(EN)The present invention relates to a thin polarizer with excellent optical properties and a method for manufacturing the same. A method for manufacturing a thin polarizer according to the present invention comprises the steps of: forming a film laminate body by attaching an unstretched polyvinyl alcohol-based film onto at least one surface of a thermoplastic polyurethane film by means of an attractive force or an adhesive; stretching the film laminate at a temperature of 45°C to 55°C; and separating the thermoplastic polyurethane film and the polyvinyl alcohol-based film.
(FR)La présente invention concerne un polariseur mince ayant d'excellentes propriétés optiques et son procédé de fabrication. Un procédé de fabrication d'un polariseur mince selon la présente invention comprend les étapes de: formation d'un corps de film laminaire par la fixation d'un film à base d'alcool polyvinylique non étiré sur au moins une surface d'un film de polyuréthane thermoplastique au moyen d'une force d'attraction ou d'un adhésif; étirement du film laminaire à une température de 45°C à 55°C; et séparation du film de polyuréthane thermoplastique et du film à base d'alcool polyvinylique.
(KO)본 발명은 광학 물성이 우수한 박형 편광자 및 그 제조 방법에 관한 것으로, 본 발명의 박형 편광자 제조 방법은 열가소성 폴리우레탄 필름의 적어도 일면에 인력 또는 접착제를 이용하여 미연신 폴리비닐알코올계 필름을 부착하여 필름 적층체를 형성하는 단계; 상기 필름 적층체를 45℃ 내지 55℃의 온도에서 연신하는 단계; 및 상기 열가소성 폴리우레탄 필름과 폴리비닐알코올계 필름을 분리하는 단계를 포함한다.
