ブチルアクリレート79質量部、エチルアクリレート15質量部、アクリル酸1質量部、2−ヒドロキシエチルアクリレート5質量部、光重合開始剤0.2質量部(イルガキュア651、50%酢酸エチル溶液)、ラウリルメルカプタン0.02質量部からなる混合液に、紫外線を照射し、重量平均分子量70000のアクリル共重合体を得た。得られたアクリル共重合体の酢酸エチル溶液の樹脂固形分100質量部に対して、メタクリル酸2−イソシアネートエチル3.5質量部を加えて反応させ、更に、反応後の酢酸エチル溶液の樹脂固形分100質量部に対して、ペンタエリスリトールトリアクリレート20質量部、光重合開始剤(イルガキュア651、50%酢酸エチル溶液)0.5質量部、ポリイソシアネート1.5質量部を混合して、UV硬化型粘着剤の酢酸エチル溶液を調製した。
まず上記UV硬化型粘着剤を、乾燥厚みが15μmとなるようにポリエステルフィルムの易接着層上に塗布して粘着剤層を形成させ、粘着テープを作成した。この粘着テープの粘着剤面を指の腹で擦り、粘着剤が取れず密着性が良好な場合を○、粘着剤層が欠落する場合を×とした。更に、このフィルムをガラス板に貼り付けた後、超高圧水銀灯を用いて、365nmの紫外線をガラス板表面への照射強度が40mW/cm2となるよう照度を調節して2分間照射した。照射後に粘着テープをガラス板から剥がした際に、ガラス板面に粘着剤が残らない場合を○、ガラス板面に粘着剤が取られて残る場合を×とした。
エポキシ変性ブロック共重合体溶液(ア)10質量部と、バインダー液(ウ)10質量部とを混合してなる塗剤を、ポリエステルフィルム(ユニチカ社製エンブレットSA−125)のコロナ処理面に塗布後、130℃で乾燥して、易接着層の形成されたポリエステルフィルムを得た。
表1に示したエポキシ変性ブロック重合体とバインダーとに変更した以外は、実施例1と同様にして、易接着層の形成されたポリエステルフィルムを得た。
