Process for making lithographic printing plate

摘要

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 using a developer comprising (Component A) an organic solvent having a solubility in water at 20° C. of 1.5 to 7.0 g/100 mL, (Component B) an amphoteric surfactant represented by Formula (I) below and/or Formula (II) below, and (Component C) water.;
