Title
(EN) EASY-ADHESION FILM FOR OPTICAL SHEET AND METHOD FOR MANUFACTURING THE SAME
(FR) FILM D'ADHESION FACILE POUR FEUILLE OPTIQUE ET SON PROCEDE DE FABRICATION

Abstract
(EN)
This invention provides a method for manufacturing an easy-adhesion film for an optical sheet, which can prevent blocking after coating of an easy-adhesion layer in a process (coating, transfer, and carrying) for forming an optical functional layer in the manufacture of an optical functional film, or a process for manufacturing an easy-adhesion support, which does not cause layer separation in handling (for example, transport, cutting, or lamination) and has excellent adhesion even in a high-temperature and high-humidity atmosphere, and a method for manufacturing the easy-adhesion film. In this method, an easy-adhesion layer coated onto the surface of a web (W) as a support contains an aqueous urethane resin and a crosslinking agent or contains a styrene-butadiene copolymer and a crosslinking agent, and the upper most layer in a back layer formed on the backside of the web (W) is a polyolefin layer.

La présente invention concerne un procédé de fabrication d'un film d'adhésion facile pour une feuille optique, permettant d'empêcher le blocage après l'enduction d'une couche d'enduction facile lors d'un procédé (enduction, transfert et support) de formation d'une couche optique fonctionnelle lors de la fabrication d'un film optique fonctionnel, ou d'un procédé de fabrication d'un support d'adhésion facile, qui ne provoque pas de séparation de couche lors de sa manipulation (par exemple, transport, coupe ou laminage) et qui présente une excellente adhésion même en une atmosphère présentant une humidité et une température élevées, ainsi qu'un procédé de fabrication du film d'adhésion facile. Selon ce procédé, une couche d'adhésion facile enduite sur la surface d'une bande (W) servant de support contient une résine aqueuse d'uréthanne et un agent de réticulation ou contient un copolymère styrène-butadiène et un agent de réticulation, et la couche supérieure d'une couche de fond formée à l'arrière de la bande (W) est une couche de polyoléfine.
