エステル交換触媒として酢酸マンガン四水塩を、重合触媒として三酸化アンチモンを用いて、固有粘度0.60dl/g(35℃、オルトクロロフェノール)のポリエチレン-2,6-ナフタレート(表4中「PEN」と示す。)を合成した。得られた樹脂を、170℃ドライヤーで6時間乾燥後、押出機に投入し、溶融温度300℃で溶融混練した。300℃のダイスリットより樹脂を押し出した後、表面温度25℃に設定したキャスティングドラム上で冷却固化させて未延伸フィルムを作製した。この未延伸フィルムを140℃に加熱したロール群に導き、長手方向に3.5倍で延伸し、25℃のロール群で冷却した。
縦延伸後のフィルムの両面に、上記易接着剤をロールコーター法により、最終的に得られる積層体における易接着層の厚みがそれぞれ50nmとなるように塗布した。続いて、フィルムの両端をクリップで保持しながらテンター内に導き、135℃に加熱された雰囲気中で横方向に3.5倍で延伸した。テンタ-内で、220℃で40秒間の熱固定を行い、220℃で幅方向に1%弛緩した後、均一に徐冷して室温まで冷やし、200μm厚みの二軸延伸フィルムを得た。
次に、得られた二軸延伸フィルムの両面の易接着層の上に、押出ラミネート法により、表4に示す組成の接着性樹脂層を形成し、積層体を得た。得られた接着性樹脂層のそれぞれの厚みは50μmであった。なお、押出ラミネートの条件は、押出温度230℃とした。

この未延伸フィルムを140℃に加熱したロール群に導き、長手方向に3.5倍で延伸し、25℃のロール群で冷却した。
続いて、縦延伸後のフィルムの両面に、実施例1と同様にして易接着剤をロールコーター法により塗布した。

得られた試験片の2枚の金属部材のうち、接着性樹脂層が接着されていない部分をそれぞれ上下チャックに固定し、金属部材と接着性樹脂層との間のはく離接着強さ(N/10mm)を測定した。測定条件は、温度が25℃、引張速度は30mm/分とした。
