A negative type photosensitive resin composition includes a polymer compound which has, in a main chain thereof, a constitutional unit A represented by Formula A-1, a constitutional unit B that is at least one of constitutional units represented by Formulae B-1, B-2, B-3, B-4, B-5, B-6, or B-7, and a constitutional unit C containing an ethylenically unsaturated group; and a polymerization initiator.
A negative type planographic printing plate precursor includes an image recording layer containing the negative type photosensitive resin composition.
A method of preparing a planographic printing plate includes, in order, an exposure step of image-exposing the negative type planographic printing plate precursor; and a development step of performing development by removing a non-exposed portion of the exposed negative type planographic printing plate precursor using a developer.
底片型感光树脂组合物包括一种聚合物化合物,其主链中具有由式 A-1 表示的构型单元 A、由式 B-1、B-2、B-3、B-4、B-5、B-6 或 B-7 表示的构型单元中至少一个构型单元 B 和含有乙烯不饱和基团的构型单元 C;以及一种聚合引发剂。
底片型平版印刷板前体包括含有底片型感光树脂组合物的图像记录层。
制备平版印刷板的方法依次包括:对底片型平版印刷板前体进行图像曝光的曝光步骤;以及使用显影剂去除已曝光的底片型平版印刷板前体的未曝光部分以进行显影的显影步骤。
