本発明のポリマーは、溶剤に溶解して樹脂溶液とし、これをシリコン、ガラス、鉄、銅、ニッケル、アルミニウム等の金属や、ガラス等の基材からなる基板上に塗布し、その後、80~300℃の範囲の温度条件で加熱し、成膜することで樹脂皮膜を与える。塗布方法としては、公知の方法でよく、ディップ法、スピンコート法、ロールコート法等が挙げられる。前記樹脂溶液中のポリマー濃度は、10~70質量%が好ましく、20~60質量%がより好ましい。前記樹脂溶液の塗布量は、目的に応じて適宜選択することができるが、得られる樹脂皮膜の膜厚が好ましくは0.1~200μm、より好ましくは1~150μmとなるように塗布することが好ましい。また、得られた樹脂皮膜は、膜厚10μmにおける波長405nmの光の透過率が95%以上と高い透明性を有していることがよく、この樹脂皮膜に高温下で光を当て続けてもオイルブリード等の問題が発生しない。
本発明の保護フィルム付きドライフィルムは、支持フィルムと、該支持フィルム上に前記樹脂皮膜と、更にその上に保護フィルムとを備えるものである。

前記方法で得られたガラスウエハー上の皮膜からなるサンプルに100℃のオーブン中で、400nm、1Wのレーザーを1,000時間当て続けて、サンプル表面の状態を確認した。このときオイルブリードが発生していたものを×、初期と比べて変化のなかったものを○とし、結果を表2に示す。
