Description
即ち、本発明によれば、ポリ塩化ビニルを主成分とする基材中に熱安定剤としてトリアルキルホスファイトを添加することにより、該トリアルキルホスファイトが粘着剤層中に移行しても長期にわたって粘着力を維持し、長期保存安定性に優れる。この為、基材と粘着剤層との間に熱安定剤の移行を防止するバリヤー層を形成する必要が無いので、ダイシング用粘着シート自体の柔軟性が損なわれるのを防止することができる。更に、その結果、バリヤー層の形成の為の工程が不要になり、製造工程の簡素化及び製造コストの低減が可能になる。
<基材フィルムの作製>
ポリ塩化ビニル樹脂100重量部、ジオクチルフタレート(DOP)30重量部、ステアリン酸バリウム0.55重量部、ステアリン酸亜鉛0.5重量部、及びトリ−(オクチル)−ホスファイト0.6重量部をカレンダー成形機にて製膜し(設定温度180℃)、厚さ100μmのポリ塩化ビニルフィルムからなる基材フィルムを得た。
アクリル酸ブチル90重量部及びアクリル酸10重量部をトルエン溶液中で常法により共重合させ、重量平均分子量50万のアクリル系共重合体を得た。このアクリル系共重合体を含有する溶液に、ポリイソシアネート化合物(商品名「コロネートL」、日本ポリウレタン(株)製)5重量部を加えて、アクリル系紫外線硬化型粘着剤溶液を調製した。

実施例1で調製した粘着剤溶液を、前記で得られた基材フィルム上に塗布し、80℃で10分間加熱架橋して、厚さ10μmの紫外線硬化型粘着剤層を形成した。次いで、当該粘着剤層面にセパレータを貼り合せて感圧ダイシング用粘着シートを作製した。

実施例1で調製した粘着剤溶液を、前記で得られた基材フィルム上に塗布し、80℃で10分間加熱架橋して、厚さ10μmの紫外線硬化型粘着剤層を形成した。次いで、当該粘着剤層面にセパレータを貼り合せて感圧ダイシング用粘着シートを作製した。
<基材フィルムの作製>
本比較例に於いては、トリ−(オクチル)−ホスファイトに代えて、ジデシル−モノアリール−ホスファイトを用いたこと以外は、前記実施例1と同様にして本実施例に係る基材フィルムを作製した。
実施例1で調製した粘着剤溶液を、前記で得られた基材フィルム上に塗布し、80℃で10分間加熱架橋して、厚さ10μmの紫外線硬化型粘着剤層を形成した。次いで、当該粘着剤層面にセパレータを貼り合せて感圧ダイシング用粘着シートを作製した。
<基材フィルムの作製>
本比較例に於いては、トリ−(オクチル)−ホスファイトに代えて、トリアリールホスファイトを用いたこと以外は、前記実施例1と同様にして本実施例に係る基材フィルムを作製した。
実施例1で調製した粘着剤溶液を、前記で得られた基材フィルム上に塗布し、80℃で10分間加熱架橋して、厚さ10μmの紫外線硬化型粘着剤層を形成した。次いで、当該粘着剤層面にセパレータを貼り合せて感圧ダイシング用粘着シートを作製した。
<基材フィルムの作製>
本参考例に於いては、トリ−(オクチル)−ホスファイトの含有量を1.5重量部に代えたこと以外は、前記実施例1と同様にして本参考例に係る基材フィルムを作製した。
実施例1で調製した粘着剤溶液を、前記で得られた基材フィルム上に塗布し、80℃で10分間加熱架橋して、厚さ10μmの紫外線硬化型粘着剤層を形成した。次いで、当該粘着剤層面にセパレータを貼り合せて感圧ダイシング用粘着シートを作製した。
