実施例1~4および比較例1、2により得られた粘着テープについて、下記の方法により、自背面保持力および耐端末剥がれ性について評価をした。結果を表1に示す。なお、比較例3および4は粘着テープを作製できなかったため自背面保持力試験および耐端末剥がれ性試験を実施しなかった。
上述した方法によって、100℃での自背面保持力(ずれ距離)を測定した。なお、1時間経過前に剥がれ落ちたものについては、剥がれ落ちるまでの時間を測定した。
このようにして測定した自背面保持力は2.0mm以下のずれ距離であることが必要である。ずれ距離が2.0mmより大きいと実用的な耐端末剥がれ性に劣り、好ましくない。
耐端末剥がれ性試験の模式図を図1に示す。厚さ2mm、縦120mm、横60mmのポリプロピレン板を縦中央位置(60mmの部分)で90°に折り曲げた(L字型)成型品を準備する(図1(a))。この成型品の横方向の中央外側に、19mm幅に切断した粘着テープを2kgローラーで1往復して貼り合せる。その際、粘着テープの一端をポリプロピレン板の内側へ、距離d1(約5mm)折り返す。さらに同じ粘着テープを貼り合せの際にテープ端末に荷重が掛かるように、成型品を内方向に曲げ(成型品端部間距離L1(85mm)がL2(70mm)となるように曲げる)、自背面への貼り合せ距離d2とd3の合計が20mm±2mmとなるよう自背面に貼り合せする(図1(b))。作製したサンプルを室温で12時間放置後、加湿下(50℃、92%RH)に投入し、7日後の粘着テープの自背面の剥がれ距離を測定し、耐端末剥がれ性試験の結果を得た。なお、7日経過前に剥がれ落ちたものについては、剥がれ落ちるまでの時間を測定した。評価基準としては、7日後の剥がれ距離が10mmより大きいと実用的な耐端末剥がれ性に劣り、好ましくない。従って、剥がれ距離が10mm以下である場合を合格(○)とし、一方、剥がれ距離が10mmより大きい場合、または7日以内に剥がれ落ちた場合を不合格(×)とした。
