Abstract:
1. A process for making a lithographic printing plate, the process comprising: a step of preparing 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 imagewisely 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 at least (Component A) a compound represented by Formula (I) below and/or Formula (II) 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, wherein in Formula (I) R
