Description
(1)酢酸ビニル及びアルキル基の炭素数が8の(メタ)アクリル酸アルキルエステルとを必須のモノマー成分とし、必要によりその他の共重合モノマーを添加して重合された粘着剤、或いは、
(2)N−ビニル−2−ピロリドン及びアルキル基の炭素数が8の(メタ)アクリル酸アルキルエステルとを必須のモノマー成分とし、必要によりその他の共重合モノマーを添加して重合された粘着剤、
が主成分として使用される。
アクリル酸−2−エチルヘキシル75%、酢酸ビニル20%及びアクリル酸ヒドロキシエチル5%を溶剤中で重合して共重合体(以下、「共重合体A」という。)を得た。この共重合体A溶液を剥離ライナー上に塗工した後、溶剤を乾燥除去して粘着剤層を形成させ、支持体であるPEFシート(厚さ1.0mm)を張り合わせて、実施例1のカバー材を得た。ここで得られたカバー材の粘着剤層は厚さが50μmであり、糸引きや舌出し等物性面の問題はみられなかった。また、カバー材のプローブタックテスターによる剥離力は106.2gFであった。
共重合体A80%と、可塑剤としてミリスチン酸イソプロピル20%とを混合し、剥離ライナー上に塗工した以外は実施例1と同様にして実施例2のカバー材を得た。得られたカバー材は、糸引きや粘着剤層の舌出し等物性面の問題はなかった。また、カバー材のプローブタックテスターによる剥離力は66.4gFであった。
アクリル酸−2−エチルヘキシル75%、酢酸ビニル20%及びアクリル酸5%を溶剤中で重合して共重合体(以下、「共重合体B」という。)を得た。この共重合体B70%と、可塑剤としてクエン酸トリエチル30%とを混合して、剥離ライナー上に塗工した以外は実施例1と同様にして実施例3のカバー材を得た。得られたカバー材の粘着剤層は厚さが50μmであり、糸引きや舌出し等物性面の問題はみられなかった。また、カバー材のプローブタックテスターによる剥離力は67.0gFであった。
アクリル酸2−エチルヘキシル80%及びN−ビニル−2−ピロリドン20%を溶剤中で重合して共重合体を得た。得られた共重合体85%と、可塑剤としてミリスチン酸イソプロピル15%とを混合して、剥離ライナー上に塗工した以外は実施例1と同様にして実施例4のカバー材を得た。得られたカバー材の粘着剤層は厚さが50μmであり、糸引きや舌出し等物性面の問題はみられなかった。また、カバー材のプローブタックテスターによる剥離力は104.8gFであった。
貼付剤の支持体フィルムを織布ラミネートの支持体を用いる以外は実施例1と同様にして比較例1のカバー材付き貼付剤を作製した。ここで、織布ラミネートとは、目付88.3g/m3で厚さ0.45mmのPET織布を、厚さ1.8μmPETフィルムに積層したものである。
共重合体Aに対し、所定量のミリスチン酸イソプロピル(IPM)を添加し、PEFシートに塗工しカバー材とした。このとき使用したPEFシートは、厚さ1mm、1.25mmの2種とした。また比較のため、厚さ25μmのPETフィルムにも塗工し、可塑剤の影響を調べた。
実施例1及び比較例1のカバー材付き貼付剤を所定の期間、所定の温度にて保存した。
メシル酸ペルゴリドを含まない他は表2と同じ組成(プラセボ)の混合物の有機溶剤(酢酸エチル、n−ヘプタン)溶液を作製して厚さ25μmのPETフィルム上に塗布して、有機溶剤を除去し、PETフィルム上に粘着剤層を形成させた。これを面積16cm2又は25cm2に切り抜いた。以下、面積16cm2のものを「プラセボ貼付剤1」、面積25cm2のものを「プラセボ貼付剤2」と呼ぶ。
