Description
また、前記光重合開始剤は、前記光酸発生剤が酸を発生しない波長域、即ち280nm以上の波長域の光で感光することができるものが好ましい。
本発明の画像形成方法は、280nm未満の波長域の光により酸を発生する光酸発生剤と電子供与性染料とを含有する感光性組成物の塗膜に対し、異なる波長域で複数回露光することにより、着色部と未着色部とからなる画像パターン(以下、「画像コントラスト」などともいう。)の形成と定着をそれぞれ行うものである。
一般に、感光波長域の強度(感度)は、その濃度に依存するため、光酸発生剤の有する感光波長域の裾が280nmにかかるものであっても、その配合量を制限することによって280nmにかかる強度を低減し、280nm以上の波長域での露光では酸を発生しない光酸発生剤として用いることができる。
さらにこれらの中でも、ArFエキシマーレーザー(193nm)、KrBrエキシマーレーザー(207nm)、KrClエキシマーレーザー(223nm)、KrFエキシマーレーザー(248nm)がより好ましい。
