Abstract:
(EN) Provided is a polarizing film with an adhesive layer, which comprises a polarizing film that is obtained by arranging a transparent protection film on at least one surface of a polarizer, with an adhesive agent layer being interposed therebetween, and an adhesive layer that is laminated on the transparent protection film. This polarizing film with an adhesive layer is characterized in that: the surface of the polarizer, on which the adhesive agent layer is disposed, is subjected to an activation treatment; the adhesive agent layer is a layer of a cured product of an adhesive agent composition; the adhesive agent composition contains an active energy ray curable component and a shrinkage inhibitor that has an M-O bond (wherein M represents silicon, titanium, aluminum or zirconium; and O represents an oxygen atom) in the structural formula; and the maximum dimensional change rate is 0.40% or less.
(FR) L'invention porte sur un film polarisant avec une couche adhésive, qui comprend un film polarisant qui est obtenu en disposant un film de protection transparent sur au moins une surface d'un polariseur, avec une couche d'agent adhésif interposée entre celles-ci, et une couche adhésive qui est stratifiée sur le film de protection transparent. Ce film polarisant avec une couche adhésive est caractérisé en ce que : la surface du polariseur, sur laquelle la couche d'agent adhésif est disposée, est soumise à un traitement d'activation; la couche d'agent adhésif est une couche d'un produit durci d'une composition d'agent adhésif; la composition d'agent adhésif contient un composant durcissable par rayonnement d'énergie active et un inhibiteur de retrait qui a une liaison M-O (dans laquelle M représente le silicium, le titane, l'aluminium ou le zirconium; et O représente un atome d'oxygène) dans la formule structurale; et le taux de changement dimensionnel maximal est de 0,40 % ou moins.
(JA) 偏光子の少なくとも一方の面に、接着剤層を介して透明保護フィルムが設けられている偏光フィルムと、透明保護フィルム側に積層された粘着層とを有する粘着層付き偏光フィルムであって、偏光子は、接着剤層が設けられる面が活性化処理されたものであり、接着剤層は、接着剤組成物の硬化物層であり、接着剤組成物は、活性エネルギー線硬化性成分、および構造式中にM-O結合(Mはケイ素、チタン、アルミニウム、ジルコニウムであって、Oは酸素原子を示す)を有する収縮防止剤を含有し、最大寸法変化率が0.40%以下であることを特徴とする粘着層付き偏光フィルム。
