反応容器内に窒素置換したイオン交換水200部を仕込み、乳化剤としてオレイン酸カリウム1部、過硫酸カリウム0.3部を仕込んだ。続いてMMA40部、BA10部、n-OM0.005部を仕込み、窒素雰囲気下65℃にて3時間撹拌し、重合を完結させた。引き続いて、MMA48部及びBA2部からなる単量体混合物を2時間にわたり滴下し、滴下終了後2時間保持し、重合を完結させた。得られたラテックスを0.25質量%硫酸水溶液に添加し、重合体を酸凝析し、その後脱水、水洗、乾燥し、粉体状で重合体を回収した。得られた熱可塑性重合体(C1)の質量平均分子量は1,000,000であった。
製造例16では、反応性基含有アクリル樹脂(B-1)として、製造例5の反応性基含有アクリル樹脂(B-1A)を100部、LA-31を2.1部、製造例15の熱可塑性重合体(C1)を2部、Chimassorb2020を0.45部、Irg1076を0.1部用い、これらをヘンシェルミキサーで混合した。次いで、これを35mmφのスクリュー型2軸押出機(L/D=26)を用いて、シリンダー温度200℃~240℃、ダイ温度240℃の条件下で溶融混練し、ペレット化して、アクリル樹脂層(II)用の樹脂組成物(B1)を得た。
実施例1では、T850、製造例17で得たアクリル樹脂層(II)用の樹脂組成物(B2)を80℃で一昼夜乾燥した。シリンダー温度を230℃に設定した30mmφの押出し機でT850を可塑化した。また、シリンダー温度を240℃に設定した400メッシュのスクリーンメッシュを設けた40mmφの押出し機で樹脂組成物(B2)を可塑化した。次いで、250℃に設定した2種2層用フィードブロックダイで、フッ素系樹脂層(I)側が鏡面冷却ロールに接するようにして、T850及び樹脂組成物(B2)を厚さ50μmの積層フィルムに製膜した。フッ素系樹脂層(I)及びアクリル樹脂層(II)の厚さはそれぞれ5μm及び45μmであった。
