各実施例及び比較例で得られた貼付剤について、それぞれ、10mm×500mmの大きさに裁断して離型ライナーを除去した貼付剤をフェノール樹脂製の試験板に貼付した試験サンプルを6つずつ準備した。先ず、6つの全試験サンプルにおいて、各貼付剤の粘着剤層の全面が試験板表面に完全に密着しており、端部も含めて容易に剥離することができない状態となっていることを確認した。
(1)付着性の耐水評価試験
入浴時などを想定した付着性の耐水評価試験として、上記6つの試験サンプルのうち3つの試験サンプルを40℃の恒温水槽に15分間浸漬させた。浸漬後の各試験サンプルにおいて、貼付剤の粘着剤層と試験板表面との付着状態を確認し、次の基準:
a:粘着剤層の全面が試験板表面に完全に密着しており、試験前と比べ、端部も含めて付着性に変化がみられなかった。
b:粘着剤層と試験板表面とが密着しているものの、試験前と比べると粘着剤層の端部の一部において付着性の低下が確認された。
c:粘着剤層と試験板表面とは付着しているものの、試験前と比べると粘着剤層の全面において付着性の低下が確認され、試験板から粘着剤層が容易に剥離されてしまう状態であった。
に従って評価した。
(2)付着性の耐湿評価試験
入浴時などを想定した付着性の耐湿評価試験として、上記6つの試験サンプルのうち残りの3つの試験サンプルを40℃、湿度75%RHの恒温恒湿器内に一晩(約15時間)放置した。放置後の各試験サンプルにおいて、貼付剤の粘着剤層と試験板表面との付着状態を確認し、上記基準に従って評価した。
先ず、ヘアレスマウス胴体部の皮膚を剥離して脂肪を除去し、表皮側に2.5cm2の大きさに切断して離型ライナーを除去した貼付剤を貼付した。これを真皮側がレセプター液に接するようにフロースルータイプのフランツ型透過試験セルにセットし、前記セルにレセプター溶液(PBS)を満たした。次いで、レセプター溶液が32℃に保温されるように、暖めた循環水を外周部に循環させながら約2.5ml/hrの流速でレセプター溶液を送液し、4時間毎に24時間までレセプター溶液を採取した。採取したレセプター溶液中のブトルファノールの濃度(酒石酸換算)を高速液体クロマトグラフ法により測定し、各時間において、粘着剤層の単位面積における1時間あたりのブトルファノール皮膚透過量(酒石酸換算、単位:μg/cm2/hr)を算出し、この最大値を最大皮膚透過速度(Jmax)とした。
先ず、酒石酸ブトルファノール6.0質量部、無水酢酸ナトリウム2.1質量部、ゴム系粘着基剤1(SIS:PIB=1:1(質量比))25.8質量部、シリコーン系粘着基剤(シリコーン粘着剤、型番:BIO-PSA7-4201、ダウ・コーニング社製)1.5質量部、粘着付与剤29.8質量部、可塑剤15.8質量部、及びその他成分(吸収促進剤及び吸着剤)19.0質量部を、適量の溶媒(無水エタノール及びトルエン)に加えて混合し、粘着剤層組成物を得た。次いで、得られた粘着剤層組成物を離型ライナー(離型処理が施されたポリエチレンテレフタレート製フィルム)上に塗布し、溶媒を乾燥除去して、単位面積あたり質量が80g/m2となるように粘着剤層を形成した。得られた粘着剤層の前記離型ライナーと反対の面上に支持体層(ポリエチレンテレフタレート製フィルム)を積層し、支持体層/粘着剤層/離型ライナーの順に積層された貼付剤を得た。
粘着剤層組成物の組成を下記の表1に示す組成となるようにしたこと以外は実施例1と同様にして、各貼付剤を得た。
粘着剤層組成物の組成を下記の表1に示す組成となるようにしたこと以外は実施例1と同様にして貼付剤を得ようとしたが、ゴム系粘着基剤1とシリコーン系粘着基剤との相溶性が悪く粘着剤層組成物が分離してしまったために、使用可能な粘着剤層を形成することができなかった。
粘着剤層組成物の組成を下記の表2に示す組成とし、粘着剤層の単位面積あたり質量(粘着剤層質量)を下記の表2に示す質量となるようにしたこと以外は、実施例1と同様にして、各貼付剤を得た。
粘着剤層組成物の組成を下記の表3に示す組成となるようにしたこと以外は、実施例1と同様にして、各貼付剤を得た。なお、表3において、ゴム系粘着基剤2は、SISとPIBとの配合質量比(SIS:PIB)が=7:3のゴム系粘着基剤を示す。
a:粘着剤層の端部も含めて粘着剤層残りは確認されなかった。
b:粘着剤層の端部の一部において粘着剤層残りが確認された。
c:粘着剤層の全面において粘着剤層残りが確認された。
に従って評価したところ、実施例11及び実施例14では評価結果がaであり、実施例12~13では評価結果がbであった。
