(帯電防止層形成用組成物の調製)
反応容器中で、イオン交換水11質量部と参考例3の水溶性ポリエステル樹脂1質量部とを撹拌混合し、更にエタノール26質量部を投入し、均一に撹拌混合した。この混合物に、更に帯電防止剤(ポリエチレンジオキシチオフェンポリスチレンスルフォネート;クレビオスP、HCスタルク(株))20質量部を添加し、更に均一に撹拌混合した。得られた混合物に、更に参考例2の縮合反応物のイソプロピルアルコール溶液42質量部を投入し、更に均一に撹拌混合することにより、帯電防止層形成用組成物を得た。
反応容器中で、硬化型シリコーン溶液(KS847、信越化学工業(株))10質量部と、白金系硬化剤(CAT-PL50T、信越化学工業(株))0.1質量部と、トルエン90質量部とを撹拌混合することによりシリコーン系剥離層形成用組成物を得た。
厚さ50μmのポリエステル基材フィルム(テトロンU2、帝人(株))の片面に、帯電防止層形成用組成物を、乾燥厚が0.1μmとなるように塗布し、160℃で1分間乾燥することにより帯電防止層を形成した。

<<評価>>
得られた実施例1及び2並びに比較例1~4の帯電防止性剥離フィルムについて、以下に説明するように初期「剥離力」、初期「残留接着力」、「表面抵抗値」、エージング前後の「密着力」を評価した。得られた結果を表1に示す。
帯電防止性剥離フィルムのシリコーン系剥離層面に、アクリル系粘着フィルム(T4090、デクセリアルズ(株))を70℃の温度下で25g/cm2の圧力で貼り合わせ、16時間経過後、剥離試験器(テンシロン万能試験機、(株)オリエンテック)で剥離力を測定した。剥離力は、実用上、2N/5cm以下、好ましくは0.6N/5cm以下であることが望まれる。
市販のポリエステル系粘着テープ(31B、日東電工(株))の帯電防止性剥離フィルムに対する「剥離力」の評価を上述のように行った後、シリコーン系剥離層と接触したポリエステル系粘着テープ面を、剥離処理されていないポリエチレンテレフタレート基材フィルム(ルミラーS10、東レ(株))に対し、同様に貼り合わせ、16時間経過後に剥離強度を測定した(剥離強度A)。これとは別に、テフロン(登録商標)フィルム上に、剥離力の評価を行っていない市販のポリエステル系粘着テープ(31B、日東電工(株))を、同様に貼り合わせ、20時間経過後に剥離し、テフロン(登録商標)フィルムを接触したポリエステル系粘着テープ面を、剥離処理されていないポリエチレンテレフタレート基材フィルム(ルミラーS10、東レ(株))に対し、同様に貼り合わせ、16時間経過後に剥離強度を測定した(剥離強度B)。そして剥離強度Aと剥離強度Bとを、以下の式(1)に代入して残留接着力を求めた。残留接着力は80%以上であることが望まれる。
帯電防止性剥離フィルムのシリコーン系剥離層側表面の表面抵抗[Ω/□]を、電気抵抗測定機(ハイレスター、(株)三菱化学アナリテック)を用いて測定した。表面抵抗値は1×1011Ω/□以上であることが望まれる。
