単体透過率(%)=(MD+TD)/2
(式中、MDは波長380nmでのMD透過率、TDは波長380nmでのTD透過率を示す。)
で定義される。ここで、「MD透過率」とは、グラントムソンプリズムから出る偏光の向きとプロテクトフィルム60のサンプルのTDとを平行にしたときの透過率であり、また「TD透過率」とは、グラントムソンプリズムから出る偏光の向きとプロテクトフィルム60のサンプルのTDとを直交させたときの透過率である。透過率は、紫外可視吸光光度計や分光光度計などにより測定することができる。
単体透過率(%)=(MD+TD)/2
(式中、MDは波長380nmでのMD透過率、TDは波長380nmでのTD透過率を示す。)
で定義される。ここでいう「MD透過率」とは、グラントムソンプリズムから出る偏光の向きとプロテクトフィルム付偏光板サンプルの透過軸とを平行にしたときの透過率であり、また「TD透過率」とは、グラントムソンプリズムから出る偏光の向きとプロテクトフィルム付偏光板サンプルの透過軸とを直交させたときの透過率である。透過率は、紫外可視吸光光度計や分光光度計などにより測定することができる。
プロテクトフィルム60は、以下の方法で作製することができる。初めに、セパレートフィルムと、該セパレートフィルム上に積層された粘着剤層(第2粘着剤層62)と、を含む粘着シートを得る。
偏光子10は、その吸収軸に平行な振動面をもつ直線偏光を吸収し、吸収軸に直交する(透過軸と平行な)振動面をもつ直線偏光を透過する性質を有する吸収型の偏光子であり、ポリビニルアルコール系樹脂フィルムに二色性色素を吸着配向させた偏光フィルムを好適に用いることができる。偏光子10は、例えば、ポリビニルアルコール系樹脂フィルムを一軸延伸する工程;ポリビニルアルコール系樹脂フィルムを二色性色素で染色することにより二色性色素を吸着させる工程;二色性色素が吸着されたポリビニルアルコール系樹脂フィルムをホウ酸水溶液で処理する工程;及び、ホウ酸水溶液による処理後に水洗する工程を含む方法によって製造できる。
偏光子10の片面又は両面に積層することができる保護フィルム21,22は、透光性を有する(好ましくは光学的に透明な)熱可塑性樹脂、例えば、鎖状ポリオレフィン系樹脂(ポリプロピレン系樹脂等)、環状ポリオレフィン系樹脂(ノルボルネン系樹脂等)のようなポリオレフィン系樹脂;トリアセチルセルロース、ジアセチルセルロースのようなセルロース系樹脂;ポリエチレンテレフタレート、ポリブチレンテレフタレートのようなポリエステル系樹脂;ポリカーボネート系樹脂;メタクリル酸メチル系樹脂のような(メタ)アクリル系樹脂;ポリスチレン系樹脂;ポリ塩化ビニル系樹脂;アクリロニトリル・ブタジエン・スチレン系樹脂;アクリロニトリル・スチレン系樹脂;ポリ酢酸ビニル系樹脂;ポリ塩化ビニリデン系樹脂;ポリアミド系樹脂;ポリアセタール系樹脂;変性ポリフェニレンエーテル系樹脂;ポリスルホン系樹脂;ポリエーテルスルホン系樹脂;ポリアリレート系樹脂;ポリアミドイミド系樹脂;ポリイミド系樹脂等からなるフィルムであることができる。中でも、ポリオレフィン系樹脂、セルロース系樹脂を用いることが好ましい。
保護フィルム21,22は、例えば接着剤層を介して偏光子10に貼合することができる。接着剤層を形成する接着剤としては、水系接着剤、活性エネルギー線硬化性接着剤、又は熱硬化性接着剤を用いることができ、好ましくは水系接着剤、活性エネルギー線硬化性接着剤である。
偏光板100は、偏光子10及び保護フィルム21,22以外の他の光学フィルムを含むことができ、その代表例は輝度向上フィルム50及び位相差フィルムである。偏光板100が他の光学フィルムを含む場合、プロテクトフィルム60は、この光学フィルムの表面に積層されてもよい。
第1粘着剤層31は、偏光板100の最表面に配置される粘着剤層であり、プロテクトフィルム付偏光板を画像表示素子(例えば液晶セル)や他の光学部材に貼合するために用いることができる。第3粘着剤層32は、偏光板100を構成する光学フィルム同士(例えば輝度向上フィルム50のような他の光学フィルムと偏光子10又は保護フィルム21)を貼合するために用いられる。第1粘着剤層31、第3粘着剤層32は、(メタ)アクリル系、ゴム系、ウレタン系、エステル系、シリコーン系、ポリビニルエーテル系のような樹脂を主成分とする粘着剤組成物で構成することができる。中でも、透明性、耐候性、耐熱性等に優れる(メタ)アクリル系樹脂をベースポリマーとする粘着剤組成物が好適である。粘着剤組成物は、活性エネルギー線硬化型、熱硬化型であってもよい。
セパレートフィルム70は、第1粘着剤層31を画像表示素子(例えば液晶セル)や他の光学部材に貼合するまでその表面を保護するために仮着されるフィルムである。セパレートフィルム70は通常、片面に離型処理が施された熱可塑性樹脂フィルムで構成され、その離型処理面が第1粘着剤層31に貼り合わされる。セパレートフィルム70を構成する熱可塑性樹脂は、例えば、ポリエチレンのようなポリエチレン系樹脂、ポリプロピレンのようなポリプロピレン系樹脂、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のようなポリエステル系樹脂等であることができる。第3粘着剤層32の表面にも、輝度向上フィルム50等の光学フィルムを貼合するまでその表面を仮着保護するために、上と同様のセパレートフィルムを貼着しておくことができる。セパレートフィルム70の厚みは、例えば10~50μmである。
本発明に係る液晶パネルは、液晶セルと、前記液晶セルのバックライト側に貼合される、上述の本発明に係るプロテクトフィルム付偏光板とを含むものである。プロテクトフィルム付偏光板は、前記液晶セルのバックライト側の面上に積層されることが好ましい。液晶パネルにおいて、プロテクトフィルム付偏光板は、その第1粘着剤層31が(セパレートフィルム70を有する場合にはこれを剥離除去した後)液晶セル側になるように配置される。プロテクトフィルム付偏光板を第1粘着剤層31を介して液晶セルに貼合した後、所望のタイミングでプロテクトフィルム60は剥離除去される。したがって、本発明に係る液晶パネルを用いて製造された液晶表示装置は、液晶表示装置の製造時の紫外線照射による液晶の劣化が防止されている一方で、最終的にはプロテクトフィルム60を含まないため、プロテクトフィルム60中の紫外線吸収剤に由来する欠陥の発生に起因する品質の低下が抑制される。
プロテクトフィルムの粘着剤層中の紫外線吸収剤の含有量、プロテクトフィルムの波長380nmにおける単体透過率、偏光板の波長380nmにおける単体透過率は、次の方法に従って測定した。以下、使用量、含有量等を表す部及び%は、特に断りのない限り重量基準である。
プロテクトフィルムの粘着剤層中の紫外線吸収剤の含有量は、プロテクトフィルムから粘着剤を掻き取り、以下の手順にて前処理を行った後、液体クロマトグラフィーにて得られたピーク面積から定量を行った。なお、プロテクトフィルムから粘着剤を掻き取る際には、溶剤を使用せずスパチュラ等の金属でできたサジを用いて行った。溶剤を使用するとその溶剤の影響によって紫外線吸収剤を含む基材フィルムから紫外線吸収剤が抽出される可能性があるため、測定精度が悪くなることが懸念される。
初めに、プロテクトフィルムから粘着剤層をスパチュラで掻き取る。次に、粘着剤層中に含まれる紫外線吸収剤を溶媒により抽出して得られた溶液を濾過洗浄を繰り返した後に濃縮し、再溶解することにより試験溶液を得る。
得られた試験溶液を液体クロマトグラフィーで測定し、紫外線吸収剤成分のピーク面積から定量化する。測定条件は、用いた紫外線吸収剤が2,2-(1,4-フェニレン)ビス[4H-3,1-ベンゾオキサジン-4-オン]、Kemisorb102(ケミプロ化成株式会社製)、アデカスタブLA31(株式会社ADEKA製)、アデカスタブLA46(株式会社ADEKA製)のときには、以下の通りである。

(紫外線吸収剤含有ポリエステルフィルムの製造)
製造例11において、ポリエステルチップと配合する紫外線吸収剤をトリアジン系紫外線吸収剤アデカスタブLA46(株式会社ADEKA製)とした以外は、製造例11と同様の方法で紫外線吸収剤含有ポリエステルフィルムを得た。厚みは154μmであった。
製造例1の乾燥後の粘着シートにおいて、トリアジン系紫外線吸収剤アデカスタブLA46(株式会社ADEKA製)を、その含有量が重量分率で135ppmとなるように加える以外は製造例1と同様の方法で粘着シートを形成した。
製造例19において、乾燥後の粘着シート中にトリアジン系紫外線吸収剤アデカスタブLA46(株式会社ADEKA製)を、その含有量が重量分率で191ppmとなるように加える以外は製造例19と同様の方法で積層体を作製した。
製造例19において、乾燥後の粘着シート中にトリアジン系紫外線吸収剤アデカスタブLA46(株式会社ADEKA製)を、その含有量が重量分率で375ppmとなるように加える以外は製造例19と同様の方法で積層体を作製した。
製造例1~21のプロテクトフィルムを用いて、プロテクトフィルム付偏光板を作製した。具体的な製造方法は下記のとおりである。
平均重合度約2400、ケン化度99.9モル%以上で厚み30μmのポリビニルアルコールフィルムを、乾式で約4倍に一軸延伸し、さらに緊張状態を保ったまま、40℃の純水に1分間浸漬した後、ヨウ素/ヨウ化カリウム/水の重量比が0.05/10/100の水溶液に28℃で60秒間浸漬した。その後、ヨウ化カリウム/ホウ酸/水の重量比が8.5/7.5/100の水溶液に68℃で300秒間浸漬した。引き続き、10℃の純水で20秒間洗浄した後、65℃で乾燥して、一軸延伸されたポリビニルアルコールフィルムにヨウ素が吸着配向している偏光フィルムを作製した。偏光フィルムの厚みは11μmであった。
以下の各成分を混合し、脱泡して、紫外線硬化性樹脂接着剤を液体状態で調製した。
1,4-ブタンジオールジグリシジルエーテル 20部、
2-エチルヘキシルグリシジルエーテル 5部、
トリアリールスルホニウム ヘキサフルオロホスフェート系の光カチオン重合開始剤、 2.25部。
製造例1~21で得られた積層体からセパレートフィルムを剥離し、厚み20μmのハードコート層を有する輝度向上フィルム〔3M(株)製の商品名「APF-V4 HC」〕に貼り合わせた。この際、プロテクトフィルムは輝度向上フィルムにおけるハードコート層上に貼り合わせた。その後、厚み5μmの光学的に透明なアクリル粘着剤を介して輝度向上フィルムと、上記(2)で得られた偏光板(両面保護フィルム付偏光板)とを貼り合わせた。偏光板における輝度向上フィルムが貼り合わせられた面とは反対側の面に、片面にセパレートフィルムを有する厚み20μmの光学的に透明なアクリル粘着剤を貼り合わせることによりプロテクトフィルム付偏光板を得た。
得られたプロテクトフィルム付偏光板をカッターにて80mm×80mmの正方形に切り出し、セパレートフィルムを剥がして、無アルカリガラスに貼合することによりガラス貼合サンプルを得た。得られたガラス貼合サンプルを60℃90%RHのオーブンに所定時間(12時間、240時間)投入した。60℃90%RHの条件に晒されることによってプロテクトフィルムの粘着剤層中に含まれる紫外線吸収剤の結晶化が加速される。
