Description
以下の各変形例において、上記した一実施形態と同様の部材および工程については、同一の参照符号を付し、その詳細な説明を省略する。また、各変形例は、特記する以外、一実施形態と同様の作用効果を奏することができる。さらに、一実施形態およびその変形例を適宜組み合わせることができる。
<アクリル系コポリマー(粘着性のベースポリマー)の調製>
アクリル酸エチル70質量部、アクリル酸2エチルヘキシル30質量部、アクリル酸ヒドロキシエチル4質量部、メタクリル酸メチル5質量部を含有するモノマー成分を、溶液重合法により共重合して、アクリル系コポリマーを調製した。なお、アクリル系コポリマーは、反応溶媒である酢酸エチル中に分散している。
<アクリル系ポリマー(粘着性のベースポリマー)の準備>
アクリル系ポリマーとして、綜研化学社製のSK1811Lを準備した。
<ガス発生粒子分散液の調製>
ガス発生粒子(永和化成社製、FE−788、ADCA粒子、ガス発生量135mL/g)20g、分散剤(共栄社化学社製、フローレンDOPA−100)10g、酢酸エチル170gを配合して、それらをビーズミルにて1時間攪拌して、ガス発生粒子分散液を調製した。
調製例1のアクリル系コポリマー100質量部、イソシアネート系架橋剤(日本ポリウレタン工業社製、コロネートL)1.4質量部、ガス発生粒子分散液200質量部(ガス発生粒子20質量部含有)、ロジンフェノール系樹脂(住友ベークライト社製、スミライトレジンPR−12603、粘着付与剤)10質量部および酢酸エチル(アクリル系コポリマーの反応溶媒を含む)を均一に混合して塗布液(ワニス)を調製した。次いで、塗布液を、基材シート(PET製セパレータ、厚み38μm)3の厚み方向一方面に乾燥後の厚みが20μmになるように塗布および乾燥して、粘着剤層2を調製した。その後、第2基材シート(PET製セパレータ、38μm)4を粘着剤層2の厚み方向一方面に貼り合わせた。これにより、図1Aに示すように、基材シート3、粘着剤層2および第2基材シート4を厚み方向一方側に向かって順に備える粘着シートを作製した。
表1に従って、ベースポリマーまたはガス発生粒子分散液の処方を変更した以外は、実施例1と同様に処理して、粘着シートを作製した。
実施例1と同様の方法により、厚み1μmの粘着剤層2を第2基材シート4の他方面に形成した。
・FE−788:ガス発生粒子、ADCA粒子、ガス発生量135mL/g(0℃、1013hPa)、永和化成社製
・ビニホールAC#3C−K2:ガス発生粒子、ADCA粒子、ガス発生量210mL/g(0℃、1013hPa)、永和化成社製
・ネオセルボンN#1000M:ガス発生粒子、OBSH粒子、ガス発生量125mL/g(0℃、1013hPa)、永和化成社製
・グリシジルアジドポリマー:下記式(1)で示さる、溶解型のガス発生剤。略称「GAP」、重量平均分子量約2000、ガス発生量20mL/g(0℃、1013hPa)、下記式中、xおよびnは、繰り返し数を示す。
各実施例および各比較例の粘着シート(、粘着剤層、第2粘着剤層)について、下記の項目を評価した。それらの結果を表1〜表3に記載する。
粘着シート1を5cm角に切り出し、その粘着剤層2を500倍の光学顕微鏡で観察した。そして、無作為に選出した20個の粒子のサイズを計測し、サイズの平均値を平均粒子径として取得した。
加熱前の粘着剤層(粘着組成物の固形物)2の25℃における引張弾性率を、JISK6922−2に従って測定した。
基材シート3を粘着剤層2の他方面から剥離し、次いで、粘着剤層2の他方面に、厚み25μmのPETシートからなる基材8を貼り合わせた後、幅20mm、長さ100mmに切断し、サンプルを作製した。
基材シート3および第2基材シート4を粘着剤層2から剥離し、粘着剤層2を試料カップに入れた後、加熱炉型パイロライザー(DSP)で加熱した。加熱条件においては、昇温速度が2℃/分で、最終温度を250℃とした。
基材シート3を粘着剤層2の他方面から剥離し、厚み100μmのPETシートからなる被着体9を貼り合わせた後、50mm角に切断し、リワーク性評価用サンプルを作製した。
○被着体9の表面全面から、粘着剤層2が剥離した。
×被着体9の表面全面からは、粘着剤層2が剥離せず、被着体9の表面の一部において浮きが観察された。
上記した剥離性の評価後に、被着体9を光学顕微鏡にて観察し、以下の基準で、汚染を評価した。
○:被着体9の表面に付着物が付着物(糊残り)として残存したことが観察されなかった。
×:被着体9の表面に粘着剤成分が付着物(糊残り)として残存したことが観察された。
