Definitions
- the present invention relates to a piece protective polarizing film provided with a protective film only on one side of a polarizer and a piece protective polarizing film with a pressure sensitive adhesive layer having a pressure sensitive adhesive layer.
- the above-mentioned piece protective polarizing film with an adhesive layer can form an image display device such as a liquid crystal display device (LCD) or an organic EL display device alone or as an optical film obtained by laminating it.
- LCD liquid crystal display device
- organic EL display device alone or as an optical film obtained by laminating it.
- polarizing films In a liquid crystal display device, it is indispensable to dispose polarizing films on both sides of a glass substrate that forms the surface of a liquid crystal panel because of its image forming method.
- a polarizing film in which a protective film is bonded to one or both sides of a polarizer made of a dichroic material such as a polyvinyl alcohol film and iodine with a polyvinyl alcohol adhesive or the like is used. .
- an adhesive is usually used.
- the polarizing film can be fixed instantaneously and has a merit such that a drying step is not required to fix the polarizing film
- the adhesive is provided in advance as an adhesive layer on one side of the polarizing film. . That is, a piece protective polarizing film with an adhesive layer is generally used for attaching the polarizing film.
- a polarizing film or a piece protective polarizing film with a pressure-sensitive adhesive layer is a polarizer in a harsh environment of a thermal shock (for example, a heat shock test in which a temperature condition of ⁇ 30 ° C. and 80 ° C. is repeated or a test at a high temperature of 100 ° C.).
- a thermal shock for example, a heat shock test in which a temperature condition of ⁇ 30 ° C. and 80 ° C. is repeated or a test at a high temperature of 100 ° C.
- a single-protective polarizing film with a pressure-sensitive adhesive layer using a single-protective polarizing film provided with a protective film only on one side of a polarizer has insufficient durability due to the thermal shock.
- the penetration crack produced by the said thermal shock was easy to generate
- the adhesive layer of the piece protective polarizing film with an adhesive layer has a storage elastic modulus at 23 ° C. of 0.2 to 10 MPa and a thickness of 2 ⁇ m to 25 ⁇ m. It has been proposed to use less than (Patent Document 1). Further, in order to suppress the occurrence of the through cracks, as the pressure-sensitive adhesive layer of the piece protective polarizing film with the pressure-sensitive adhesive layer, the shrinkage force in the direction perpendicular to the absorption axis of the polarizer is controlled to be small, and the pressure-sensitive adhesive layer It has been proposed to use one having a storage elastic modulus at 23 ° C. of 0.20 MPa or more (Patent Document 2). Thinning is also performed for polarizers, and for example, a thin polarizer exhibiting high orientation in which optical characteristics of single transmittance and polarization degree are controlled has been proposed (Patent Document 3).
- Patent Document 1 Although the durability is satisfied, since the thickness of the polarizer is as large as 25 ⁇ m, it is not possible to prevent the occurrence of through cracks due to the contraction stress of the polarizer. Moreover, since patent document 1, 2 makes it the subject to improve the durability of the piece protection polarizing film with an adhesive layer, the boric acid used for a polarizer is comparatively much. When the amount of boric acid contained in the polarizer is greater than a specific value, crosslinking with boric acid is promoted during heating, and the contraction stress of the polarizer increases, which is not preferable from the viewpoint of suppressing the occurrence of through cracks. I also understood that. That is, in Patent Documents 1 and 2, through cracks can be prevented to some extent by controlling the storage elastic modulus of the pressure-sensitive adhesive layer, but it cannot be said that the occurrence of through cracks can be sufficiently suppressed.
- thinning is also done for polarizers.
- the polarizer used for the piece protective polarizing film with the pressure-sensitive adhesive layer is thinned, the change in the contraction stress of the polarizer becomes small. Therefore, it has been found that the thinned polarizer can suppress the occurrence of the through cracks.
- the nano slit does not occur when both protective polarizing films having protective films on both sides of the polarizer are used.
- the stress around the through crack is released, so the through crack does not occur adjacently. I found it to happen.
- the penetration crack has the progressive property extended in the absorption-axis direction of the polarizer in which the crack generate
- the nano slit is a new problem that occurs when the polarizer is thin and the optical characteristics are controlled within a predetermined range in the single-protective polarizing film in which the generation of through cracks is suppressed. It has been found that this is a problem caused by a phenomenon different from the above-described through crack.
- the nano slit is extremely thin, it cannot be detected under a normal environment. Therefore, even if nano-slits are generated in the polarizer, it is difficult at first glance to confirm defects due to light leakage in the adhesive protective layer-attached piece protective polarizing film. That is, usually, the piece-protecting polarizing film is produced in the form of a long film and automatically inspected for defects by optical inspection, but it is difficult to detect nanoslits as defects by this defect inspection.
- the defect due to the nano slit can be detected by spreading the nano slit in the width direction when the piece protective polarizing film with an adhesive layer is attached to the glass substrate of the image display panel and then placed in a heating environment. It was also found that (for example, the presence or absence of light leakage).
- the piece protective polarizing film with a pressure-sensitive adhesive layer using a thin polarizer it is desired to suppress not only through cracks but also defects due to nano slits. Furthermore, since the single protective polarizing film with an adhesive layer is thinner than a polarizing film having a protective film on both sides, the polarizing film is likely to be broken or broken during handling.

等に記載されている薄型偏光子またはこれらに記載の製造方法から得られる薄型偏光子を挙げることができる。
P>-(100.929T-42.4-1)×100(ただし、T<42.3)、又は、
P≧99.9(ただし、T≧42.3)の条件を満足するように構成されている。前記条件を満足するように構成された偏光子は、一義的には、大型表示素子を用いた液晶テレビ用のディスプレイとして求められる性能を有する。具体的にはコントラスト比1000:1以上かつ最大輝度500cd/m2以上である。他の用途としては、例えば有機EL表示装置の視認側に貼り合される。
前記保護フィルムを構成する材料としては、透明性、機械的強度、熱安定性、水分遮断性、等方性などに優れるものが好ましい。例えば、ポリエチレンテレフタレートやポリエチレンナフタレートなどのポリエステル系ポリマー、ジアセチルセルロースやトリアセチルセルロースなどのセルロース系ポリマー、ポリメチルメタクリレートなどのアクリル系ポリマー、ポリスチレンやアクリロニトリル・スチレン共重合体(AS樹脂)などのスチレン系ポリマー、ポリカーボネート系ポリマー等が挙げられる。また、ポリエチレン、ポリプロピレン、シクロ系ないしはノルボルネン構造を有するポリオレフィン、エチレン・プロピレン共重合体の如きポリオレフィン系ポリマー、塩化ビニル系ポリマー、ナイロンや芳香族ポリアミドなどのアミド系ポリマー、イミド系ポリマー、スルホン系ポリマー、ポリエーテルスルホン系ポリマー、ポリエーテルエーテルケトン系ポリマー、ポリフェニレンスルフィド系ポリマー、ビニルアルコール系ポリマー、塩化ビニリデン系ポリマー、ビニルブチラール系ポリマー、アリレート系ポリマー、ポリオキシメチレン系ポリマー、エポキシ系ポリマー、または上記ポリマーのブレンド物なども上記保護フィルムを形成するポリマーの例として挙げられる。
前記保護フィルムと偏光子は接着剤層、粘着剤層、下塗り層(プライマー層)などの介在層を介して積層される。この際、介在層により両者を空気間隙なく積層することが望ましい。前記保護フィルムと偏光子は接着剤層を介して積層するのが好ましい。
本発明の粘着剤層付片保護偏光フィルムにおける粘着剤層は、前記のように、膜厚と貯蔵弾性率が前記式を満足するように制御される。粘着剤層の膜厚は50μm未満である。
リワーク性及び加熱耐久性(加熱時の剥がれ抑制)の観点からは、粘着剤層は柔らかい方が好ましく、粘着剤層の膜厚は、例えば、30μm以下が好ましく、さらには25μm以下が好ましい。なお、粘着剤層の膜厚は、剥がれ抑制の観点から1μm以上であることが好ましく、さらには5μm以上であることが好ましい。さらには、パネル等に貼り合せる時の異物の噛み込み不良を抑制する観点からは、粘着剤層は厚い方が好ましく、例えば、10μm以上、さらには15μm以上が好ましい。
粘着剤層付片保護偏光フィルムには、表面保護フィルムを設けることができる。表面保護フィルムは、通常、基材フィルムおよび粘着剤層を有し、当該粘着剤層を介して偏光子を保護する。
本発明の粘着剤層付片保護偏光フィルムは、実用に際して他の光学層と積層した光学フィルムとして用いることができる。その光学層については特に限定はないが、例えば反射板や半透過板、位相差板(1/2や1/4などの波長板を含む)、視角補償フィルムなどの液晶表示装置などの形成に用いられることのある光学層を1層または2層以上用いることができる。特に、本発明の粘着剤層付片保護偏光フィルムに更に反射板または半透過反射板が積層されてなる反射型偏光フィルムまたは半透過型偏光フィルム、粘着剤層付片保護偏光フィルムに更に位相差板が積層されてなる楕円偏光フィルムまたは円偏光フィルム、粘着剤層付片保護偏光フィルムに更に視角補償フィルムが積層されてなる広視野角偏光フィルム、あるいは粘着剤層付片保護偏光フィルムに更に輝度向上フィルムが積層されてなる偏光フィルムが好ましい。
上記の画像表示装置は、本発明の粘着剤層付片保護偏光フィルムの巻回体(ロール)から繰り出され、前記セパレータにより搬送された前記粘着剤層付片保護偏光フィルムを、前記粘着剤層を介して画像表示パネルの表面に連続的に貼り合せる工程を含む連続製造方法(ロール・トゥ・パネル方式)にて製造されることが好ましい。本発明の粘着剤層付片保護偏光フィルムは非常に薄いフィルムであるため、シート状に切断(枚葉切断)したうえで画像表示パネルに1枚ずつ貼り合せる方式(「シート・トゥ・パネル方式」ともいう。)によると、シートの搬送や表示パネルへの貼合せ時のハンドリングが難しく、それらの過程で粘着剤層付片保護偏光フィルム(シート)が大きな機械的衝撃(例えば、吸着による撓み等)を受けるリスクが高くなる。このようなリスクを低減するには、例えば基材フィルムの厚みが50μm以上の厚めの表面保護フィルムを用いる等の対策が別途必要となる。一方、ロール・トゥ・パネル方式によれば、粘着剤層付片保護偏光フィルムがシート状に切断(枚葉切断)されることなく、連続状のセパレータによりロールから画像表示パネルまで安定的に搬送され、そのまま画像表示パネルに貼り合わされるため、厚めの表面保護フィルムを用いることなく、上記リスクを大幅に低減することができる。その結果、膜厚と貯蔵弾性率が所定の関係式を満足するように制御した粘着剤層により機械的衝撃を緩和することができることと相まって、ナノスリットの発生が効果的に抑制された画像表示パネルを高速連続生産することができる。
液晶表示装置の連続製造システム100は、図7に示すように、液晶表示パネルPを搬送する一連の搬送部X、第1偏光フィルム供給部101a、第1貼合部201a、第2偏光フィルム供給部101b、及び第2貼合部201bを含む。

第1偏光フィルム供給部101aは、第1ロール20aから繰り出され、セパレータ5aにより搬送された第1粘着剤層付片保護偏光フィルム(表面保護フィルム付)21aを第1貼合部201aに連続的に供給する。第1偏光フィルム供給部101aは、第1繰出部151a、第1切断部152a、第1剥離部153a、第1巻取部154a、および複数の搬送ローラ部、ダンサーロール等のアキュムレート部等を有する。

第2偏光フィルム供給部101bは、第2ロール20bから繰り出され、セパレータ5bにより搬送された第2粘着剤層付片保護偏光フィルム(表面保護フィルム付)21bを第2貼合部201bに連続的に供給する。第2偏光フィルム供給部101bは、第2繰出部151b、第2切断部152b、第2剥離部153b、第2巻取部154b、および複数の搬送ローラ部、ダンサーロール等のアキュムレート部等を有する。なお、第2繰出部151b、第2切断部152b、第2剥離部153b、第2巻取部154bは、それぞれ第1繰出部151a、第1切断部152a、第1剥離部153a、第1巻取部154aと同様の構成および機能を有する。
第2貼合部201bは、搬送部Xによって搬送された液晶表示パネルPに、第2剥離部153bによって剥離された第2粘着剤層付片保護偏光フィルム21bを、第2粘着剤層付片保護偏光フィルム21bの粘着剤層を介して連続的に貼り合わせる(第2貼合工程)。第2貼合部201bは、一対の貼合ローラを有して構成され、貼合ローラの少なくとも一方が駆動ローラで構成される。

攪拌羽根、温度計、窒素ガス導入管、冷却器を備えた4つ口フラスコに、ブチルアクリレート63部およびメチルメタクリレート37部を含有するモノマー混合物を仕込んだ。さらに、前記モノマー混合物(固形分)100部に対して、重合開始剤として2,2´-アゾビスイソブチロニトリル0.1部をトルエンと共に仕込み、緩やかに攪拌しながら窒素ガスを導入して窒素置換した後、フラスコ内の液温を60℃付近に保って7時間重合反応を行った。その後、得られた反応液に、トルエンを加えて、固形分濃度30%に調整した、重量平均分子量10万のアクリル系ポリマーの溶液を調製した。

得られた片保護偏光フィルムの単体透過率Tおよび偏光度Pを、積分球付き分光透過率測定器(村上色彩技術研究所のDot-3c)を用いて測定した。
なお、偏光度Pは、2枚の同じ片保護偏光フィルムを両者の透過軸が平行となるように重ね合わせた場合の透過率(平行透過率:Tp)および、両者の透過軸が直交するように重ね合わせた場合の透過率(直交透過率:Tc)を以下の式に適用することにより求められるものである。偏光度P(%)={(Tp-Tc)/(Tp+Tc)}1/2×100
各透過率は、グランテラープリズム偏光子を通して得られた完全偏光を100%として、JIS Z8701の2度視野(C光源)により視感度補整したY値で示したものである。
実施例および比較例で得られた偏光子について、フーリエ変換赤外分光光度計(FTIR)(Perkin Elmer社製、商品名「SPECTRUM2000」)を用いて、偏光を測定光とする全反射減衰分光(ATR)測定によりホウ酸ピーク(665cm-1)の強度および参照ピーク(2941cm-1)の強度を測定した。得られたホウ酸ピーク強度および参照ピーク強度からホウ酸量指数を下記式により算出し、さらに、算出したホウ酸量指数から下記式によりホウ酸含有量(重量%)を決定した。
(ホウ酸量指数)=(ホウ酸ピーク665cm-1の強度)/(参照ピーク2941cm-1の強度)
(ホウ酸含有量(重量%))=(ホウ酸量指数)×5.54+4.1
23℃における貯蔵弾性率は、レオメトリック社製の粘弾性スペクトロメータ(商品名:RSA-II)を用いて行った。測定条件は、周波数1Hz、サンプル厚2mm、圧着加重100g、昇温速度5℃/minでの-50℃~200℃の範囲に於ける、23℃での測定値とした。
実施例及び比較例で得られたアクリル系粘着剤組成物について、各実施例、比較例と同じ乾燥条件(温度、時間)で処理して粘着剤層を形成し、さらに温度23℃、湿度65%RHの条件に5日間放置した後、当該粘着剤層を0.2gとり、あらかじめ重量を測定したフッ素樹脂フィルム(TEMISH NTF-1122、日東電工(株)製)(重量:Wa)に包み、アクリル系粘着剤組成物が漏れないように縛った。これを、測定サンプルとする。測定サンプルの重量を測定し(重量:Wb)、サンプル瓶にいれた。サンプル瓶に酢酸エチルを40cc加えて、7日間放置した。その後、測定サンプル(フッ素樹脂フィルム+アクリル系粘着剤組成物)を取り出し、当該測定サンプルをアルミカップ上で、130℃、2時間乾燥させた。測定サンプルの重量(Wc)を測定し、次式によりゲル分率を求めた。
得られた粘着剤層付片保護偏光フィルムを、50mm×150mm(吸収軸方向が50mm)と150mm×50mm(吸収軸方向が150mm)に裁断し、0.5mm厚の無アルカリガラスの両面にクロスニコルの方向に貼り合せてサンプルを作成した。当該サンプルを、-40~85℃のヒートショックを各30分間×300回の環境下に投入した後に、取り出して粘着剤層付片保護偏光フィルムに貫通クラック(本数)が発生しているか否かを目視にて確認した。この試験を5回行った。評価はクラックの発生しなかった場合を「〇」、発生した場合を「×」として評価した。
得られた粘着剤層付片保護偏光フィルムを、50mm×150mmのサイズ(吸収軸方向が50mm)に裁断したものをサンプル11とした。サンプル11は、保護フィルム2の側に、下記方法で作製した表面保護フィルム6を貼り合わせて用いた。
190℃におけるメルトフローレートが2.0g/10minである密度0.924g/cm3の低密度ポリエチレンから成る基材層成形材料を共押出用インフレーション成形機に供給した。
同時に230℃におけるメルトフローレートが10.0g/10minである密度0.86g/cm3のプロピレン-ブテン共重合体(質量比でプロピレン:ブテン=85:15、アタクチック構造)から成る粘着剤層成形材料とをダイス温度が220℃であるインフレーション成形機に供給して共押出成形を行った。
これにより、厚み33μmの基材層と厚み5μmの粘着剤層とから成る表面保護フィルムを製造した。
次いで、サンプル11を80℃の環境下に1時間放置した後に、下記の基準により、サンプル11の光抜けのクラックの有無を確認した。
◎:0~30個
○:31~200個
△:201~800個
×:801個以上
片保護偏光フィルムとして長尺状のものを用いたこと、形成材をマイクログラビアコーターを用いて塗工したこと、上記の離型シート(セパレータ)及び下記の表面保護フィルムとして長尺状のものを用いたこと以外は、実施例10と同様である。これにより、片保護偏光フィルムの偏光子側にセパレータ及び透明保護フィルム側に表面保護フィルムが積層された粘着剤層付片保護偏光フィルム(図1の態様)の巻回体を作製した。なお、粘着剤層付片保護偏光フィルムの巻回体は、粘着剤層付片保護偏光フィルムの連続搬送により切断を進行させるスリット加工によって、32インチ無アルカリガラスの短辺及び長辺に各々対応する幅のものをセットとして準備した。
帯電防止処理層付きポリエチレンテレフタレートフィルム(商品名:ダイアホイルT100G38、三菱樹脂社製、厚さ38μm)の帯電防止処理面とは反対の面にアクリル系粘着剤を厚さが15μmとなるように塗布形成し、表面保護フィルムを得た。
粘着剤層付片保護偏光フィルムが両面に貼り合わされた無アルカリガラス100枚を80℃のオーブンに24時間投入し、その後目視にてナノスリットの発生の有無を確認した。ナノスリットによる欠陥(光抜け)の発生は見られなかった。
