調製例1.アクリル系共重合体
窒素ガスが還流され、容易な温度調節のための冷却装置が設置された1Lの反応器に、n−ブチルアクリレート(BA)97重量部、2−ヒドロキシエチルアクリレート(2HEA)2重量部及びアクリル酸(AA)0.5重量部、2−カルボキシエチルアクリレート(2CEA)0.5重量部からなる単量体混合物を投入した後、溶媒としてエチルアセテート(EA)100重量部を投入した。その後、酸素を除去するために窒素ガスを1時間投入して反応器を置換した後、温度を62℃に維持した。単量体混合物を均一に撹拌した後、反応開始剤としてアゾビスイソブチロニトリル(AIBN)0.07重量部を投入して8時間反応させ、重量平均分子量が50万以上のアクリル系共重合体を調製した。
(1)粘着剤組成物
固形分含有量を基準として、調製例1のアクリル系共重合体100重量部、架橋剤としてトリメチロールプロパンのトリレンジイソシアネート付加体(COR−L、日本ポリウレタン工業製)0.5重量部、シランカップリング剤として3−グリシドキシプロピルトリメトキシシラン(KBM−403、信越化学製)1重量部、安定剤として酢酸(AcA)0.5重量部を混合した後、コーティング性を考慮して25%濃度に希薄し、粘着剤組成物を調製した。
調製した粘着剤組成物をシリコーン離型剤がコーティングされたフィルム上に乾燥した後、厚さが25μmになるように塗布し、100℃で1分間乾燥させて粘着剤層を形成した。その上に他の一層の離型フィルムをラミネートし、粘着シートを製造した。
製造した粘着シートの離型フィルムを剥離した後、厚さ185μmのヨウ素系偏光板に、粘着剤層を粘着加工して積層し、粘着剤が粘着された偏光板を製造した。
前記実施例1と同様に実施し、粘着剤組成物の成分及び含有量を下記表1のように用いた。ここで、含有量は重量部である。
前記実施例及び比較例において調製した粘着剤組成物及び粘着剤が粘着された偏光板の物性を下記の方法を用いて測定し、その結果を下記表2に示した。
調製した粘着剤組成物の初期粘度と、常温で24時間放置した後の粘度とを、粘度測定計(Brookfield LVDV―II+B型(spindle no.3, 30rpm))を用いて測定した。測定した粘度の変化率(△η)を計算し、下記基準に基づいて評価した。
○:5%≦△η<10%
△:5%≦△η<15%
×:15%≦△η
調製した粘着剤が粘着された偏光板を25mm×150mmのサイズで切断して離型フィルムを剥離した後、ガラス基板(#1737、コーニング社)に0.25MPaの圧力でラミネートし、オートクレーブ処理を施して試片を作製した。常温粘着力は、作製した試片を23℃、50%RHの条件下で24時間放置した後に、加温粘着力は、試片を50℃、50%RHの条件下で48時間放置した後に、万能引張試験機(UTM、Instron)を用いて剥離速度300mm/分、剥離角度180°で粘着剤層を剥離して測定した。ここで、測定は23℃、50%RHの条件下で実施した。
調製した粘着剤が粘着された偏光板を90mm×170mmのサイズで切断して離型フィルムを剥離した後、ガラス基板(110mm×190mm×0.7mm)の両面に光学吸収軸が直交するように付着し、試片を作製した。この時、加えられた圧力は5Kg/cm2であり、気泡や異物が生じないようにクリーンルーム作業を行った。耐熱特性は、80℃の温度で1000時間放置した後、気泡や剥離の発生有無を観察し、耐湿熱特性は、60℃の温度及び90%RHの条件下で1000時間放置した後、気泡や剥離の発生有無を観察した。ここで、試片の状態を評価する直前に、常温で24時間放置した後観察した。
◎:気泡や剥離なし
○:気泡や剥離<5個
△:5個≦気泡や剥離<10個
×:10個≦気泡や剥離
調製した粘着剤が粘着された偏光板を23℃、65%RHで1日間養生した。精秤した250メッシュの鉄網(100mm×100mm)に粘着剤が粘着された偏光板の粘着剤層を約0.25g貼付し、ゲル分が漏れ出さないように包んだ。精密天秤で重量を正確に測定した後、鉄網をエチルアセテート溶液に3日間浸漬した。浸漬した鉄網を取り出して少量のエチルアセテート溶液で洗浄し、120℃で24時間乾燥した後、重量を測定した。測定した重量を用い、下記数学式1でゲル分率を計算した。
ゲル分率(%)=(C−A)/(B−A)×100
〔式中、Aは、鉄網の重量(g)、Bは、粘着剤層を貼付した鉄網の重量(B−A:粘着剤重量、g)、Cは、浸漬後に乾燥した鉄網の重量(C−A:ゲル化した樹脂の重量、g)である。〕
