    • A process for making a lithographic printing plate is provided that includes a step of producing a negative-working lithographic printing plate precursor comprising, above a support, a photopolymerizable photosensitive layer comprising a vinylcarbazole compound-derived monomer unit-containing acrylic polymer and/or a urethane-acrylic hybrid polymer, a step of imagewise exposing the negative-working lithographic printing plate precursor, and a step of developing the exposed negative-working lithographic printing plate precursor by means of a developer having a pH of 4 to 10, comprising (Component A) a compound represented by Formula (I) below and (Component B) water, and having an organic solvent content of less than 5 mass%, wherein the process does not comprise a washing step or a gumming step before or after the development step. In Formula (I), R 1 denotes a substituted or unsubstituted phenyl group, 1-naphthyl group, or 2-naphthyl group, and n denotes an integer of 4 to 20.
    • 提供了一种制备平版印刷版的方法,其包括制备负性平版印刷版原版的步骤,该负型工程平版印刷版前体在载体上方包括含有乙烯基咔唑化合物衍生的含单体单元的丙烯酸类聚合物和/或 氨基甲酸酯 - 丙烯酸类杂化聚合物,将负性平版印刷版原版成像曝光的步骤,以及通过pH为4〜10的显影剂显影曝光的负性平版印刷版原版的步骤,其包含(组分 A)由下式(I)表示的化合物和(组分B)水,并且有机溶剂含量小于5质量%,其中该方法在显影步骤之前或之后不包括洗涤步骤或上胶步骤 。 式(I)中,R 1表示取代或未取代的苯基,1-萘基或2-萘基,n表示4〜20的整数。
