Title

Abstract
(EN)
This polarizing film with an adhesive layer comprises an iodine-base polarizing element, a transparent protective film on only one side of the polarizing element, and a transparent layer on the other side of the polarizing element, and comprises an adhesive layer with the aforementioned transparent layer therebetween. The adhesive layer is used bonded on a transparent conductive layer of a transparent conductive substrate, which comprises a transparent substrate and said transparent conductive layer. The change ratio of the resistance value of the polarizing film with the adhesive layer to that of the transparent conductive layer is a prescribed change ratio. Even in the case that the adhesive layer is bonded to the transparent conductive layer and placed in a humidified environment, it is possible to maintain a stable surface resistance value of the transparent conductive layer.

Ce film polarisant avec une couche adhésive comprend un élément polarisant à base d'iode, un film protecteur transparent sur un seul côté de l'élément polarisant et une couche transparente sur l'autre côté de l'élément polarisant. Il comprend une couche adhésive avec la couche transparente susmentionnée entre elles. La couche adhésive est utilisée liée sur une couche conductrice transparente d'un substrat conducteur transparent, qui comprend un substrat transparent et ladite couche conductrice transparente. Le rapport de changement de la valeur de résistance du film polarisant avec la couche adhésive à celle de la couche conductrice transparente est un rapport de changement prescrit. Même dans le cas où la couche adhésive est liée à la couche conductrice transparente et placée dans un environnement humidifié, il est possible de maintenir une valeur de résistance de surface stable de la couche conductrice transparente.
