前記透明フィルムの片面または前記偏光フィルムの片面もしくは両面に、活性エネルギー線硬化型の接着剤を塗布するための接着剤塗工装置と、
前記透明フィルムが前記偏光フィルムの片面または両面に前記接着剤を介して積層されてなる積層体を、搬送しながら挟圧することにより、前記透明フィルムと前記偏光フィルムとを貼合するための一対の貼合ロールと、

前記押圧ロールの中央部の直径は、該押圧ロールに接する前記貼合ロールの中央部の直径よりも大きいことを特徴とする、偏光板の製造装置にも関する。
本発明の偏光板に用いられる偏光フィルムは、具体的には、一軸延伸した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ものである。ポリビニルアルコール系樹脂は、ポリビニル酢酸系樹脂をケン化することにより得られる。ポリ酢酸ビニル系樹脂としては、酢酸ビニルの単独重合体であるポリ酢酸ビニルの他に、酢酸ビニルとこれに共重合可能な他の単量体との共重合体(例えば、エチレン−酢酸ビニル共重合体)などが挙げられる。酢酸ビニルと共重合可能な他の単量体としては、他に、不飽和カルボン酸類、オレフィン類、ビニルエーテル類、不飽和スルホン酸類、アンモニウム基を有するアクリルアミド類などが挙げられる。ポリビニルアルコール系樹脂のケン化度は、85モル%以上、好ましくは90モル%以上、より好ましくは98〜100モル%である。ポリビニルアルコール系樹脂の平均重合度は、通常1000〜10000、好ましくは1500〜5000である。これらのポリビニルアルコール系樹脂は、変性されていてもよく、たとえばアルデヒド類で変性されたポリビニルホルマール、ポリビニルアセタール、ポリビニルブチラールなども使用し得る。
0μmなどがある。
本発明において、上述した偏光フィルムの片面または両面には透明フィルムが貼合される。偏光フィルムの両面に透明フィルムが貼合される場合、各々の透明フィルムは同じものであってもよく、異なる種類のフィルムであってもよい。
偏光フィルムと透明フィルムとは、活性エネルギー線硬化型の接着剤を介して貼合される。活性エネルギー線硬化型の接着剤としては、耐候性や屈折率、カチオン重合性などの観点から、活性エネルギー線の照射により硬化するエポキシ樹脂を含有するエポキシ系樹脂組成物からなる接着剤が挙げられる。ただし、これに限定されるものではなく、従来から偏光板の製造に使用されている各種の活性エネルギー線硬化型の接着剤(有機溶剤系接着剤、ホットメルト系接着剤、無溶剤型接着剤など)が採用可能である。活性エネルギー線硬化型の接着剤としては、たとえばアクリルアミド、アクリレート、ウレタンアクリレート、エポキシアクリレートなどのアクリル系樹脂組成物からなる接着剤が挙げられる。
(i)次式(IX)で示されるエポキシシクロペンチルエーテル類:
上記例示した脂環式エポキシ樹脂の中でも、次の脂環式エポキシ樹脂は、市販されているか、またはその類似物であって、入手が比較的容易である等の理由からより好ましく用いられる。
(B)4−メチル−7−オキサビシクロ[4.1.0]ヘプタン−3−カルボン酸と(4−メチル−7−オキサ−ビシクロ[4.1.0]ヘプト−3−イル)メタノールとのエステル化物[式(I)において、R1=4−CH3、R2=4−CH3の化合物]、
(C)7−オキサビシクロ[4.1.0]ヘプタン−3−カルボン酸と1,2−エタンジオールとのエステル化物[式(II)において、R3=R4=H、n=2の化合物]、
(D)(7−オキサビシクロ[4.1.0]ヘプト−3−イル)メタノールとアジピン酸とのエステル化物[式(III)において、R5=R6=H、p=4の化合物]、
(E)(4−メチル−7−オキサビシクロ[4.1.0]ヘプト−3−イル)メタノールとアジピン酸とのエステル化物[式(III)において、R5=4−CH3、R6=4−CH3、p=4の化合物]、
(F)(7−オキサビシクロ[4.1.0]ヘプト−3−イル)メタノールと1,2−エタンジオールとのエーテル化物[式(V)において、R9=R10=H、r=2の化合物]。
次に図面を参照しながら本発明の偏光板の製造装置および製造方法を説明する。図1は本発明の偏光板の製造装置の一実施形態を示す概略図である。
透明フィルム2,3への接着剤の塗工方法は特に限定されないが、例えば、ドクターブレード、ワイヤーバー、ダイコーター、カンマコーター、グラビアコーターなど、種々の塗工方式が利用できる。このうち、薄膜塗工、パスラインの自由度、幅広への対応などを考慮すると、接着剤塗工装置11,12としてはグラビアロールが好ましい。
本工程では、まず、ロール状に巻回された状態から連続的に繰り出された偏光フィルム1の両面に、上記工程により接着剤が塗布された透明フィルム11,12が接着剤を介して積層される。
活性エネルギー線の照射により接着剤の重合硬化を行うために用いる光源は、特に限定されないが、波長400nm以下に発光分布を有する光源であることが好ましい。このような光源としては、例えば、低圧水銀灯、中圧水銀灯、高圧水銀灯、超高圧水銀灯、ケミカルランプ、ブラックライトランプ、マイクロウェーブ励起水銀灯、メタルハライドランプが挙げられる。
組成物への光照射強度が10mW/cm2未満であると、反応時間が長くなりすぎ、50
00mW/cm2を超えると、ランプから輻射される熱および組成物の重合時の発熱により、接着剤の構成材料であるエポキシ樹脂組成物などの黄変や偏光フィルムの劣化を生じる可能性がある。なお、照射強度は、好ましくは光カチオン重合開始剤の活性化に有効な波長領域における強度であり、より好ましくは波長400nm以下の波長領域における強度であり、さらに好ましくは波長280〜320nmの波長領域における強度である。
ように並べる方法などが挙げられる。
積層体(偏光板)4を巻き取る張力を30N/cm2〜150N/cm2とする。好ましくは、30N/cm2〜120N/cm2である。30N/cm2未満では長尺のロール巻
きを移送する際、巻きズレが起きるため好ましくない。150N/cm2より大きい場合
は、巻き締まりが強く、タルミが発生し易い。
(偏光フィルムの作製)
ポリビニルアルコールの原反フィルムとしては、重合度2400、ケン化度99.9モル%、厚み75μm、幅3000mmの長尺のポリビニルアルコールフィルム「ビニロンVF−PS#7500(クラレ製)」を用いた。延伸は、処理槽前後の駆動ニップロールに周速差をつけて行った。
透明フィルムとして、厚さ50μmのシクロオレフィン系樹脂フィルム「ゼオノア(ZEONOR)」(日本ゼオン(株)製)と厚さ80μmのトリアセチルセルロースフィルム「KC8UX2MW」(コニカミノルタ社製)とを準備した。
実施例1の貼合ロールのニップ圧を、富士フィルム製ツーシートタイプのプレスケール(超低圧用)を用いて測定したところ、ニップ圧の分布は幅方向にほぼ均一であった。また、作製した偏光板を評価したところ、気泡は観察されなかった。結果を表1に示す。
本実施例において、貼合ロールの平均ニップ圧が2.25MPaとなるようにニップした以外は、実施例1と同様にして偏光板を作製した。
(貼合ロールのニップ圧分布および偏光板の気泡の評価)
実施例2の貼合ロールのニップ圧を、富士フィルム製ツーシートタイプのプレスケール(超低圧用)を用いて測定したところ、ニップ圧の分布は幅方向にほぼ均一であった。また、作製した偏光板を評価したところ、気泡は観察されなかった。結果を表1に示す。
一対の貼合ロールのみを用いて平均ニップ圧が1.13MPaとなるようにニップした以外は、実施例1と同様にして偏光板を作製した。
(貼合ロールのニップ圧分布および偏光板の気泡の評価)
比較例1の貼合ロールのニップ圧を、富士フィルム製ツーシートタイプのプレスケール(超低圧用)を用いて測定したところ、ニップ圧の幅方向の分布が大きかった。また、作製した偏光板を評価したところ、気泡が観察された。結果を表1に示す。
