Description
本発明の偏光フィルムは、偏光子の片面に当該偏光子中の水分の排出を助ける浸透膜として機能する第一透明層を有する。当該第一透明層の高温高湿環境下における飽和水分率は、偏光子の飽和水分率よりも低く設計されているため、環境雰囲気中の水分が偏光子中に侵入したとしても、偏光子中の水分を、偏光子の飽和水分率よりも低い飽和水分率を有する第一透明層（浸透膜）側へ積極的に透過させることができ、当該作用により偏光子中の水分を偏光子外に排出することができる。一方、前記偏光子の他の片面には、飽和水分率が５重量％以下の第二透明層を有しており、当該低飽和水分率の第二透明層によって偏光子への水分の侵入を抑制するとともに、前記偏光子Ｐからの水分拡散を妨げて、第一透明層（浸透膜）側へ偏光子の水分を透過させることができる。このように、本発明の偏光フィルムは、前記第一透明層および第二透明層を有することで、高温高湿環境下においても偏光子の飽和水分率の上昇を抑制することができ、偏光フィルムの端部色抜け量を抑制することができる。 The polarizing film of this invention has the 1st transparent layer which functions as a permeable film which assists discharge | emission of the water | moisture content in the said polarizer on the single side | surface of a polarizer. The saturated moisture content of the first transparent layer in a high-temperature and high-humidity environment is designed to be lower than the saturated moisture content of the polarizer, so even if moisture in the ambient atmosphere has entered the polarizer, Can be actively transmitted to the first transparent layer (permeation membrane) side having a saturation moisture content lower than the saturation moisture content of the polarizer, and the action allows moisture in the polarizer to be removed from the polarizer. Can be discharged. On the other hand, the other surface of the polarizer has a second transparent layer having a saturated moisture content of 5% by weight or less, and the second transparent layer having a low saturated moisture content prevents moisture from entering the polarizer. It suppresses, the preventing moisture diffusion from the polarizer P, it is possible to transmit the water content of the polarizer to the first transparent layer (osmosis) side. Thus, the polarizing film of the present invention has the first transparent layer and the second transparent layer, so that an increase in the saturated moisture content of the polarizer can be suppressed even under a high temperature and high humidity environment. The amount of color loss at the end can be suppressed.
以下に本発明の偏光フィルムを、図１乃至図４を参照しながら説明する。
本発明の偏光フィルムは、例えば、図１乃至図４に示す偏光フィルム１１のように、偏光子Ｐおよび第一透明層１（浸透膜：水の排出を助ける機能を有する膜機能を有する層）を有する。なお、図１乃至図４では、偏光子Ｐの片側に第一透明層１を有し、他の片側に飽和水分率が５重量％以下の第二透明層２の構成を有する場合を例示している。また、図１乃至図４に示すように、第一透明層１は偏光子Ｐに、直接、設けることが高温高湿環境下における偏光子の飽和水分率の上昇を抑制して、偏光フィルムの端部色抜けを抑える点から好ましい。
Hereinafter, the polarizing film of the present invention will be described with reference to FIGS. 1 to 4.
The polarizing film of the present invention includes, for example, a polarizer P and a first transparent layer 1 (penetrating membrane: a layer having a function of helping discharge of water ) like the polarizing film 11 shown in FIGS. having. 1 to 4 exemplify a case in which the first transparent layer 1 is provided on one side of the polarizer P and the second transparent layer 2 having a saturated moisture content of 5% by weight or less is provided on the other side. ing. Further, as shown in FIGS. 1 to 4, the first transparent layer 1 is provided directly on the polarizer P to suppress an increase in the saturated moisture content of the polarizer in a high temperature and high humidity environment. It is preferable from the viewpoint of suppressing color loss at the end.
