Novel photosensitive compositions based on azlactone derived polymers are described. The polymers have a hydrocarbyl backbone and pendant peptide groups with free-radically polymerizable functionality attached thereto, said polymer further comprising at least one oxyacid group or salt thereof, and optionally quaternary ammonium salt groups. A high speed durable printing plate having a mild pH aqueous developability is disclosed which incorporates these polymers in combination with a photoinitiator. The polymers are also useful as proofing films in graphic arts applications.
本文描述了基于氮内酯衍生聚合物的新型光敏组合物。这些聚合物具有烃基骨架和附有可自由基聚合官能团的悬垂肽基,所述聚合物还包括至少一个氧酸基团或其盐,以及可选的季
铵盐基团。本发明公开了一种具有温和 pH 值
水性显影能力的高速耐久印版,它将这些聚合物与光
引发剂结合在一起。这些聚合物还可用作图形艺术应用中的打样薄膜。
