Abstract
An on-press development type lithographic printing plate precursor has a support, an image-recording layer, and an outermost layer in this order. The image-recording layer contains an infrared absorber, an electron-accepting polymerization initiator, and a polymerizable compound. LUMO of the electron-accepting polymerization initiator-LUMO of the infrared absorber is 0.45 eV or more, and the outermost layer contains a discoloring compound. A method of preparing a lithographic printing plate and a lithographic printing method employ the on-press development type lithographic printing plate precursor.
