メチルイソブチルケトン 100質量部
ネガ型感光性樹脂組成物はスピンコート法によって塗布し、ホットプレート上にて90℃で3分間の加熱を行い、型材10上で10μmの厚みとした。その後、マスクアライナーMPA600FA(商品名、キヤノン製)を用い、フォトマスクを介して3000mJ/cm2の露光量で紫外線を照射した。その後、90℃で180秒の加熱を行い、硬化させた。そしてメチルイソブチルケトン/キシレン=2/3(質量比)溶液を用いて現像処理を行い、キシレンを用いてリンス処理を行うことで、吐出口4aを形成した。
図5に示すようにして、構造体を製造した。
層11の厚みを平均13nmとした以外は実施例3と同様にして、構造体を製造した。表面1a上の第2の層(層8と層11とが積層した層)のi線に対する反射率は12%以上であった。
層8の厚みを平均45nm、層11の厚みを平均17nmとした以外は実施例3と同様にして、構造体を製造した。凹部内の第1の層(層8の1層)のi線に対する反射率は39.2%であった。表面1a上の第2の層(層8と層11とが積層した層)のi線に対する反射率は51.2%であった。
層8の厚みを700nm〜980nm、平均840nmとした以外は実施例1と同様にして、構造体を製造した。層8のi線に対する反射率は25.1%であった。
層8の厚みを49nm〜69nm、平均59nmとした以外は実施例1と同様にして、構造体を製造した。層8のi線に対する反射率は57.4%であった。
層8の厚みを159nm〜221nm、平均190nmとした以外は実施例1と同様にして、構造体を製造した。層8のi線に対する反射率は53.1%であった。
