Title (EN) OPTICAL LAMINATE
(FR) STRATIFIÉ OPTIQUE
(JA) 光学積層体
Abstract:
(EN) [Problem] To provide an optical laminate which is capable of preventing deterioration of a conductive layer by effectively suppressing migration of a dichroic dye that is contained in a polarizing film to the conductive layer. [Solution] An optical laminate which is obtained by sequentially laminating, on one surface of a polarizing film that contains a dichroic dye in a polyvinyl alcohol resin, a first cured product layer that is configured from a cured product of a curable composition containing a polymerizable compound, an adhesive layer and a conductive layer in this order, and wherein the absorbance increase rate of the first cured product layer as expressed by formula (1) is 30% or less. Absorbance increase rate (%) = (Abs after immersion (360 nm) – Abs before immersion (360 nm))/Abs before immersion (360 nm) × 100 (1)
(FR) Le problème décrit par la présente invention est de fournir un stratifié optique qui est susceptible d'empêcher la détérioration d'une couche conductrice par suppression efficace de la migration d'un colorant dichroïque qui est contenu dans un film polarisant sur la couche conductrice. La solution selon l'invention porte sur un stratifié optique qui est obtenu par stratification séquentielle, sur une surface d'un film polarisant qui contient un colorant dichroïque dans une résine d'alcool polyvinylique, une première couche de produit durci qui est configurée à partir d'un produit durci d'une composition durcissable contenant un composé polymérisable, une couche adhésive et une couche conductrice dans cet ordre, et le taux d'augmentation d'absorbance de la première couche de produit durci tel qu'exprimé par la formule (1) étant de 30 % ou moins. Taux d'augmentation d'absorbance (%) = (Abs. après immersion (360 nm)- Abs. avant immersion (360 nm))/Abs. avant immersion (360 nm) × 100 (1)
(JA) [課題]偏光フィルムに含まれる二色性色素の導電層への移行を有効に抑制し、導電層の劣化を防止できる光学積層体を提供する。 [解決手段]ポリビニルアルコール系樹脂中に二色性色素を含有する偏光フィルムの一方の面に、重合性化合物を含む硬化性組成物の硬化物から構成される第1硬化物層と、粘着層と、導電層とがこの順に積層された光学積層体であって、 前記第1硬化物層は、下記式(1)で表される吸光度上昇率が30%以下である、光学積層体。 吸光度上昇率(%)=(浸漬後Abs(360nm)-浸漬前Abs(360nm))/浸漬前Abs(360nm)×100 (1)
