Abstract
Description
本発明は、ポリビニルアルコール系樹脂に二色性色素が吸着配向された偏光子の片面または両面に設けられる保護層として使用可能な転写媒体、それを用いた偏光板、及びその偏光板を少なくとも１枚含む、液晶表示装置、有機ＥＬ表示装置、ＰＤＰ等の画像表示装置に関する。 The present invention relates to a transfer medium that can be used as a protective layer provided on one or both sides of a polarizer in which a dichroic dye is adsorbed and oriented on a polyvinyl alcohol resin, a polarizing plate using the same, and at least one polarizing plate. The present invention relates to image display devices such as liquid crystal display devices, organic EL display devices, and PDPs.
液晶表示装置には、液晶パネル表面を形成するガラス基板の両側に偏光板が設置されている。偏光板は、一般的にはポリビニルアルコール（ＰＶＡ）系フィルムとヨウ素などの二色性色素からなる偏光子の両面に、偏光子保護フィルムをポリビニル系接着剤により貼り合せたものとが用いられている。特に表示装置表面側に使用される偏光子保護フィルムについては、透明基材上に、画像の視認性を向上させるために、表面反射光を拡散し、外光の正反射を抑え、外部環境の写り込みを防ぐことができる（防眩性を有する）微細凹凸構造を形成させた光学積層体などの機能層を有するものが使用されており、その透明基材として、現在、光学的透明性や取り扱いに優れるＴＡＣフィルムが主に用いられている。
そして、偏光子への貼り合わせ時に、偏光子保護フィルムの偏光子との貼り合わせ面の反対面が、貼り合わせ装置のロール等により損傷することを防ぐ目的で、カバーフィルムが偏光子保護フィルムに貼り合わせられている。
In a liquid crystal display device, polarizing plates are installed on both sides of a glass substrate that forms the surface of a liquid crystal panel. In general, a polarizing plate is obtained by bonding a polarizer protective film with a polyvinyl adhesive on both sides of a polarizer made of a polyvinyl alcohol (PVA) film and a dichroic dye such as iodine. Yes. Especially for the polarizer protective film used on the display device surface side, in order to improve the visibility of the image on the transparent substrate, the surface reflected light is diffused, the regular reflection of the external light is suppressed, and the external environment What has a functional layer such as an optical laminate formed with a fine concavo-convex structure capable of preventing reflection (having antiglare properties) is currently used as a transparent substrate, A TAC film excellent in handling is mainly used.
And, at the time of bonding to the polarizer, the cover film is made into the polarizer protective film for the purpose of preventing the opposite surface of the polarizer protective film from the bonding surface with the polarizer from being damaged by the roll of the bonding apparatus. It is pasted together.
近年、液晶表示装置のノート型パーソナルコンピュータ、携帯電話、カーナビゲーションなどのモバイル機器への展開に伴い、液晶表示装置を構成する偏光板には、薄型軽量化および高耐久性（高い機械的強度）が求められるようになっている。また、モバイル用途の液晶表示装置では、湿熱下でも使用可能であることが要望され、これに使用される偏光板についても、高い耐湿熱性が要求されているが、従来、偏光板が高湿下、特に高温高湿下に長期間晒されると、偏光性能が低下したり、偏光子の伸縮により額縁故障（引用文献１、引用文献２）などが発生し、画像表示装置の画質が低下するという問題を有していた。したがって、偏光子に積層される保護層には、薄型軽量化とともに、硬度を高くして、機械的強度を向上させるなど偏光子の伸縮を抑制する機能（伸縮抑制力）が求められている。 In recent years, with the development of liquid crystal display devices in mobile devices such as notebook personal computers, mobile phones, car navigation systems, etc., the polarizing plates that make up liquid crystal display devices are thinner and lighter and have higher durability (high mechanical strength). Is now required. In addition, liquid crystal display devices for mobile use are required to be usable under wet heat, and polarizing plates used therefor are also required to have high heat and humidity resistance. In particular, when exposed to high temperature and high humidity for a long period of time, polarization performance deteriorates, frame failure (cited document 1, cited document 2) occurs due to expansion and contraction of the polarizer, and the image quality of the image display device is degraded. Had a problem. Therefore, the protective layer laminated on the polarizer is required to have a function of suppressing the expansion and contraction of the polarizer (stretching suppression force) such as reducing the thickness and weight, increasing the hardness, and improving the mechanical strength.
従来偏光子の保護フィルムとして好適に使用されているＴＡＣフィルムは、上記問題に対しある程度効果を示しているが、高価な上、保護フィルムの厚みが薄い場合には、有効性を維持することが困難であった。 A TAC film that has been suitably used as a protective film for polarizers in the past has been effective to some extent with respect to the above problems, but is expensive and can maintain its effectiveness when the protective film is thin. It was difficult.
偏光子を保護するために偏光子に直接保護層を塗工する方法も考えられるが、薄膜で機械的強度に劣る偏光子に、直接塗工により安定して均一した塗膜を得るのは極めて困難であり、しかも、塗工液の溶剤は偏光子を溶解しない溶剤に限られるため、塗工性向上のためのレベリング性改善などの手段にも限界があり、塗工によって保護層を設ける提案の実現性は極めて乏しいものといえる。 In order to protect the polarizer, a method of applying a protective layer directly to the polarizer may be considered, but it is extremely difficult to obtain a stable and uniform coating film by direct coating on a polarizer that is thin and inferior in mechanical strength. It is difficult, and since the solvent of the coating solution is limited to the solvent that does not dissolve the polarizer, there are limits to the means for improving leveling to improve the coating properties, and a proposal to provide a protective layer by coating The feasibility of is very poor.
特許文献３には、未硬化の電離放射線硬化型樹脂層を透明支持基体の片面に設け、偏光子の片面に電離放射線硬化型樹脂層面を貼り合わせた後、活性光線照射、硬化させて、透明支持基体剥離し、電離放射線硬化型樹脂よりなる保護層を偏光子上に設ける方法が開示されている。保護層の厚さの大部分を構成する、高価なＴＡＣフィルム偏光子上に設置しない点で、画像表示装置の薄型軽量化に貢献する可能性がある。 In Patent Document 3, an uncured ionizing radiation curable resin layer is provided on one side of a transparent support substrate, and the ionizing radiation curable resin layer surface is bonded to one side of a polarizer, and then irradiated with actinic light and cured to be transparent. A method is disclosed in which a support substrate is peeled off and a protective layer made of an ionizing radiation curable resin is provided on a polarizer. There is a possibility of contributing to reduction in the thickness and weight of the image display device in that it is not placed on an expensive TAC film polarizer that constitutes most of the thickness of the protective layer.
しかしながら、未硬化の樹脂層を有するフィルムの取り扱いは難しく、特に偏光板製造の工程では連続生産する都合上、保護フィルムのロールでの取り扱いが要求されるため、さらに難しいものとなる。そして、電離放射線としては、その取り扱いの容易性から紫外線が用いられており、画像表示装置用途の偏光板に使用される保護フィルムに求められる紫外線吸収機能を与えることが、非常に困難である。 However, it is difficult to handle a film having an uncured resin layer. In particular, in the process of producing a polarizing plate, handling with a roll of a protective film is required for the convenience of continuous production. And as an ionizing radiation, ultraviolet rays are used from the ease of the handling, and it is very difficult to provide the ultraviolet-absorbing function requested | required of the protective film used for the polarizing plate for an image display apparatus use.

The thickness of the support is preferably thin from the viewpoint of weight reduction, but considering the productivity, it is preferable to use a support in the range of 1 to 100 μm.
上記支持体の表面は各種の表面処理が施されていてもよい。特に転写媒体との剥離性を増す為に真空中でフッ素系化合物を用いて表面をプラズマ処理する方法、大気中で高温の熱処理を行ない支持体の表面にオリゴマーを滲出す方法、窒素ガス雰囲気中で電子線を照射し支持体表面を変質させる方法、支持体の製膜工程において、アクリル樹脂系、ポリビニルアルコール系、ポリオレフィン系等の異種支持体を積層し、表面を改質する方法等が用いられる。表面処理後の表面エネルギーは、５０ｄｙｎｅ／ｃｍ以下、特に好ましくは２０ｄｙｎｅ／ｃｍであることが望ましい。 Various surface treatments may be applied to the surface of the support.

（離型層）
本発明の転写媒体において、必要に応じ適宜採用される離型層は、支持体とその上に形成される転写媒体との界面において剥離しにくい場合に支持体上に形成される。従って離型層は転写媒体との界面において容易に剥離することが要件である。離型層を構成する樹脂としては、例えばエポキシ−メラミン樹脂、アクリル−メラミン樹脂、メラミン樹脂、アクリル樹脂、尿素樹脂、尿素−メラミン樹脂、シリコーン樹脂、アクリル−シリコーン樹脂、フッ素樹脂系、各種ワックス類等があげられる。これらの樹脂の１種又はそれ以上の樹脂の有機溶剤溶液、エマルジョン等のコーティング剤をロールコーティング法、グラビアコーティング法等の通常コーティング法により支持体上に塗布し、溶媒を乾燥、硬化（熱硬化、電子線硬化、紫外線硬化等）することによって形成する。
(Release layer)
In the transfer medium of the present invention, the release layer that is appropriately employed as necessary is formed on the support when it is difficult to peel off at the interface between the support and the transfer medium formed thereon. Therefore, it is a requirement that the release layer be easily peeled off at the interface with the transfer medium. Examples of the resin constituting the release layer include epoxy-melamine resins, acrylic-melamine resins, melamine resins, acrylic resins, urea resins, urea-melamine resins, silicone resins, acrylic-silicone resins, fluororesins, and various waxes. Etc.

離型層の厚さは、通常０．１〜１０μｍの範囲、好ましくは０．２５〜５μｍの範囲から適宜選択実施される。離型層の厚さが０．１μｍより薄い場合には、剥離が重く目的とする剥離性を得ることができないので好ましくない。一方、１０μｍより厚い場合には剥離が軽すぎる為に、離型層上に順次形成する、転写媒体を構成する各層が加工工程中で脱落する可能性があるので好ましくない。 The thickness of the release layer is appropriately selected from the range of usually 0.1 to 10 μm, preferably 0.25 to 5 μm. When the thickness of the release layer is less than 0.1 μm, it is not preferable because peeling is heavy and the desired peelability cannot be obtained. On the other hand, when the thickness is larger than 10 μm, the peeling is too light, and therefore, each layer constituting the transfer medium, which is sequentially formed on the release layer, may fall off during the processing step.
又、離型層は、次ぎの方法によっても形成することができる。水酸基、エーテル基、カルボキシル基、アミノ基等を１個以上有する水溶性有機物質、例えばポリビニルアルコール、ポリビニルピロリドン等のビニル系水溶性樹脂、メチルセルロース、カルボキシルメチルセルロース、ヒドロキシエチルセルロース、ヒドロキシプロピルセルロース等の繊維素エーテル系樹脂、アクリル酸ソーダ、アクリル酸アンモニウム等のアクリル酸系水溶性物質、澱粉、デキストリン、ニカワ、ゼラチン等の天然水溶性物質、カゼイン、カゼイン酸ソーダ、カゼイン酸アンモニウム等のタンパク質系水溶性物質、その他ポリエチレンオキサイド、カラギーナン、グルコマンガン等の１種又はそれ以上の物質の水溶液のコーティング剤をロールコーティング法、グラビアコーティング法等の通常コーティング法により支持体上に塗布し、乾燥することによって形成する。 The release layer can also be formed by the following method.

Was applied onto the body, it is formed by drying.
これらの水溶性離型層を形成した場合は、その上に積層された転写媒体を、接着剤を用いて偏光子に転写した後、水溶性離型層と転写媒体との界面において剥離ができずに支持体と水溶性離型層の間で剥離して、水溶性離型層が残っても水洗によって水溶性離型層を完全に除去することにより、転写媒体を露出することができる。 When these water-soluble release layers are formed, the transfer medium laminated thereon can be transferred to a polarizer using an adhesive, and then peeled off at the interface between the water-soluble release layer and the transfer medium. Without being peeled between the support and the water-soluble release layer, the transfer medium can be exposed by completely removing the water-soluble release layer by washing even if the water-soluble release layer remains.
