Title (EN) POLARIZING PLATE
(FR) PLAQUE POLARISANTE
(JA) 偏光板
Abstract:
(EN) Provided is a polarizing plate that has excellent optical durability even in a high-temperature, high-humidity environment. Provided is a polarizing plate that is a cured substance layer of a curable composition, the polarizing plate including, in the stated order, a polarizer and a first cured substance layer, wherein the first cured substance layer includes an oxazoline-group-containing polymer (A), a compound (B) that has a carboxyl group, and a compound (C) for accelerating the reaction between the oxazoline group of the oxazoline-group-containing polymer (A) and the carboxyl group of the compound (B).
(FR) La présente invention concerne une plaque polarisante qui présente une excellente durabilité optique, même dans un environnement à haute température et humidité élevée. La présente invention concerne une plaque polarisante qui est une couche de substance durcie d’une composition durcissable, la plaque polarisante comprenant, dans l’ordre indiqué, un polariseur et une première couche de substance durcie, la première couche de substance durcie comprenant un polymère contenant un groupe oxazoline (A), un composé (B) qui comporte un groupe carboxyle, et un composé (C) pour accélérer la réaction entre le groupe oxazoline du polymère contenant un groupe oxazoline (A) et le groupe carboxyle du composé (B).
(JA) 高温高湿環境下においても光学耐久性が良好な偏光板を提供する。 偏光子と第1硬化物層とをこの順に含む偏光板であって、第1硬化物層はオキサゾリン基含有重合体(A)と、カルボキシル基を有する化合物(B)と、オキサゾリン基含有重合体(A)のオキサゾリン基と化合物(B)のカルボキシル基との反応を促進させる化合物(C)とを含む硬化性組成物の硬化物層である偏光板が提供される。
