Abstract
A process for making a lithographic printing plate enables a one-bath processable lithographic printing plate having excellent printing durability, ink laydown and resistance to staining during printing. The process includes a step of producing a negative-working lithographic printing plate precursor having, above a support, a photopolymerizable photosensitive layer containing a vinylcarbazole compound-derived monomer unit-containing acrylic polymer and/or a urethane-acrylic hybrid polymer, a step of image-wise 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) and/or Formula (II) below and (Component B) water, and having an organic solvent content of less than 5 mass %. The process does not comprise a washing step or a gumming step before or after the development step.
