実施例1に係る粘着剤組成物を、コンマコーターで、50μm厚のポリエステルフィルム(東洋紡(株)製、商品名「コスモシャインA−4100」)(以下、A4100)上に、10μmの膜厚になるよう塗布し、この塗工面と38μm厚の軽剥離処理ポリエステルフィルム(パナック(株)製、商品名「SP−PET−01−38BU」)(以下、剥離PET)を剥離処理面が接するよう貼り合わせた後、120W/cmの高圧水銀ランプ(岩崎電気(株)製)を用いて、38μmの軽剥離処理ポリエステルフィルム側から、900mJ/cm2の紫外線を照射し、軽剥離処理ポリエステルフィルム/粘着剤層(10μm)/A4100からなる保護シートを作製した。実施例2〜13及び比較例1〜7、9〜10に係る粘着剤組成物についても同様にして保護シートを作製した。
前記保護シートの軽剥離処理ポリエステルフィルムを剥がし、ガラス板に2kgローラーで貼り合わせて、積層体(A4100/粘着剤層/ガラス板)を作製し、温度25℃、湿度50%の条件で24時間放置した。次いで、市販の試験機(AND(株)製、テンシロン万能材料試験機)を用いて、積層体をガラス板から180°方向に300mm/minの速度で剥離して、粘着力(mN/25mm)を測定した。数値が小さいほど低粘着力に優れることを示す。結果を表2に示す(以下同様)。
前記保護シートから50mm×50mmの測定試料を切り出した。温度23℃、湿度50%の雰囲気下でこの測定試料から軽剥離処理ポリエステルフィルムを剥がし、次いで、シートの両端部を両手で把持しながら粘着剤層の露出した表面の中心部をガラス板に接触させた後、両手を離した。シートの自重で粘着剤層の全体がガラス板に密着するまでの時間を測定し、以下の基準でガラス板に対する自己吸着性を評価した。ガラス板と密着するまでの時間が短いほど部材に対してなじみやすい(自己吸着性に優れる)ことを示す。
(評価基準)
○:3秒未満(良好)
△:3秒以上5秒未満(実用可能)
×:5秒以上(実用不可能)
前記保護シートから軽剥離処理ポリエステルフィルムを剥がし、ガラス板に粘着剤層の面を2kgローラーで貼り合わせて、積層体(A−4100/粘着剤層/ガラス板)を作製し、これを温度25℃、湿度50%の雰囲気下で24時間放置した。前記積層体のヘイズ値と、これを温度85℃、湿度85%の恒温恒湿槽中に500時間静置した後のヘイズ値とを、カラーへイズメーター(村上色彩技術研究所製)を用いて、JIS K 5400に準拠し測定した。なお、得られたヘイズ値は、部材(A−4100及びガラス板)のヘイズ値を含めた値である。
前記積層体を、温度85℃、湿度85%の恒温恒湿槽中に500時間静置した後、粘着剤層の耐久性を以下の基準で評価した。
○:部材の剥がれ、粘着剤層位置のズレ、粘着剤層中の気泡、粘着剤層の破損のいずれもなし
×:部材の剥がれ、粘着剤層位置のズレ、粘着剤層中の気泡、粘着剤層の破損の少なくとも1つの欠陥が発生
項目1の粘着力を測定した後のガラス板表面における糊残りの状態を目視で確認し、粘着剤層の移行性を評価した。評価基準は以下の通りである。
○:糊残りがない
△:部分的にやや糊残りがある
×:ガラス板の表面全体に糊残りがある
実施例8〜10、比較例3、4、8の紫外線硬化型粘着剤組成物を用いて、粘着剤層の厚みを100μmと変更して、評価例1と同様の方法で軽剥離処理ポリエステルフィルム/粘着剤層/A4100の順からなる保護シートを作製し、同様に評価した。結果を表3に示す。
