Abstract
【解決手段】ポリビニルアルコール系樹脂からなる偏光フィルムの少なくとも一方の面にシクロオレフィン系樹脂フィルムを貼り合わせて偏光板を製造するにあたり、そのシクロオレフィン系樹脂フィルムの偏光フィルムに貼り合わされる側の面に、800W以下の出力強度でコロナ放電処理を施し、その処理面に接着剤を介して前記偏光フィルムを貼り合わせる。得られる偏光板に粘着剤層を形成する場合も、そのシクロオレフィン系樹脂フィルムの表面に800W以下の出力強度でコロナ放電処理を施し、その処理面に粘着剤層を形成する。
【選択図】図1
Description
平均重合度約2,400、ケン化度99.9モル%以上で厚さ75μm のポリビニルアルコールフィルムを、乾式で約5倍に一軸延伸し、さらに緊張状態を保ったまま、60℃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 0.05/5/100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8.5/8.5/100の水溶液に72℃で300秒間浸漬した。引き続き26℃の純水で20秒間洗浄した後、65℃で乾燥して、ポリビニルアルコール樹脂にヨウ素が吸着配向された偏光フィルムを得た。
水100部に、カルボキシル基変性ポリビニルアルコール((株)クラレ製の“クラレポバール KL318”)3部と水溶性ポリアミドエポキシ樹脂(住友化学(株)製の“スミレーズレジン 650”(固形分濃度30%の水溶液) 1.5部を添加して、ポリビニルアルコール系接着剤とした。
ノルボルネン系樹脂からなる厚さ73μm の延伸フィルムを用意し、その片面にコロナ放電処理を施した。その際、コロナ出力強度を 500〜2,000Wの間で変化させ、また積算照射量を2〜11kJ/m2の間で変化させ、フィルム表面への微粉末状物質発生の有無を観察した。
製造例1で得られた偏光フィルムの片面に、実施例1で得られた延伸ノルボルネン系樹脂フィルムのコロナ処理面を、他方の面には、表面ケン化処理が施されたトリアセチルセルロースからなる厚さ80μm の保護フィルムを、それぞれ製造例2で作製したポリビニルアルコール系接着剤を介して貼合し、50〜80℃の温度で5分間乾燥した。その後、40℃の環境下で7日間養生して、偏光板を得た。次いで、この偏光板のノルボルネン系樹脂フィルム面に、実施例1と同じコロナ処理装置を用いてコロナ放電処理を施した。このとき、コロナ出力強度は 500〜2,000Wの間で変化させ、また積算照射量は3〜8kJ/m2の間で変化させ、フィルム表面への微粉末状物質発生の有無を観察した。
