Abstract (en)

Provided are a lithographic printing plate precursor having excellent crystal precipitation suppressiveness, and a method of preparing a lithographic printing plate and a lithographic printing method in which the lithographic printing plate precursor is used.A lithographic printing plate precursor including a support and an image-recording layer on the support, in which the image-recording layer contains a non-onium-based polymerization initiator, a borate compound, an infrared absorber, and a compound A which is an onium salt with a cation having a shape index equal to or less than 2 times a shape index of a cationic moiety of the infrared absorber.
