Title (EN) POLARIZING SHEET AND POLARIZING LENS PROVIDED WITH SAME
(FR) FEUILLE POLARISANTE ET LENTILLE POLARISANTE COMPRENANT CELLE-CI
(JA) 偏光性シート、及びこれを備えた偏光レンズ
Abstract:
(EN) Provided is a polarizing sheet which is free from the occurrence of a white spot even if subjected to bending, and which is able to be provided with a desired curved shape with high accuracy. A polarizing sheet according to the present invention has a configuration wherein a polyamide resin film (1), a polarizing film and a polyamide resin film (2) are sequentially laminated in this order, and is characterized in that: the retardation value of the polyamide resin film (1) is 10-3,000 nm; and the retardation value of the polyamide resin film (1) and the retardation value of the polyamide resin film (2) satisfy formula (r). (Retardation value of polyamide resin film (1)) - (Retardation value of polyamide resin film (2)) ≥ 10 nm (r)
(FR) La présente invention concerne une feuille polarisante qui est exempte d’apparition d’un point blanc même si elle est soumise à une flexion, et qui peut être pourvue d’une forme incurvée souhaitée avec une précision élevée. Une feuille polarisante selon la présente invention a une configuration dans laquelle un film de résine de polyamide (1), un film polarisant et un film de résine de polyamide (2) sont séquentiellement stratifiés dans cet ordre, et est caractérisée en ce que : la valeur de retard du film de résine de polyamide (1) est de 10 à 3 000 nm ; et la valeur de retard du film de résine de polyamide (1) et la valeur de retard du film de résine de polyamide (2) satisfont à la formule (r). (Valeur de retard du film de résine de polyamide (1))- (valeur de retard du film de résine de polyamide (2)) ≥ 10 nm (r)
(JA) 曲げ加工を施しても白抜けを生じることなく、且つ精度よく所望の曲面形状を付与することができる偏光性シートを提供する。 本発明の偏光性シートは、ポリアミド樹脂フィルム(1)、偏光フィルム、及びポリアミド樹脂フィルム(2)がこの順で積層された構成を有し、前記ポリアミド樹脂フィルム(1)のレタデーション値が10~3000nmであり、且つ、前記ポリアミド樹脂フィルム(1)とポリアミド樹脂フィルム(2)のレタデーション値が下記式(r)を満たすことを特徴とする。 [ポリアミド樹脂フィルム(1)のレタデーション値]-[ポリアミド樹脂フィルム(2)のレタデーション値]≧10nm (r)
