There is provided a photosensitive resin composition which enables production of a lithographic printing plate precursor having a non-image portion which has good solubility in an alkali aqueous solution and which enables production of a lithographic printing plate having excellent printing durability, excellent chemical resistance, and, in particular, excellent printing durability at the time of using a low quality print material, a lithographic printing plate precursor obtained by using the photosensitive resin composition, and a method for producing a lithographic printing plate.
The photosensitive resin composition contains a polymer compound having a linking group represented by Formula A-1 in the main chain; and an infrared absorbing material. In Formula A-1, R1 and R2 each independently represent a hydrogen atom or a monovalent organic group, and X1 is a specific linking group.
本发明提供了一种感光树脂组合物,该组合物能够生产出具有非图像部分的平版印刷版前体,该非图像部分在碱水溶液中具有良好的溶解性,并且能够生产出具有出色的印刷耐久性、出色的耐化学性,尤其是在使用低质量印刷材料时具有出色的印刷耐久性的平版印刷版;还提供了一种通过使用该感光树脂组合物获得的平版印刷版前体,以及一种平版印刷版的生产方法。
感光树脂组合物包含一种高分子化合物,其主链中具有由式 A-1 表示的连接基团;以及一种红外线吸收材料。在式 A-1 中,R1 和 R2 各自独立地代表一个氢原子或一个一价有机基团,X1 是一个特定的连接基团。
