ABSTRACT:
A lithographic printing plate precursor, which comprises: a support; an image-recording layer; and a protective layer, in this order, wherein at least one of the image-recording layer and the protective layer comprises a phosphonium salt having a specific structure, and a lithographic printing process, which comprises: exposing a lithographic printing plate precursor; supplying an oil-based ink and a fountain solution comprising a phosphonium salt having a specific structure to the exposed lithographic printing plate precursor on a printing machine to remove an unexposed area of an image-recording layer; and conducting printing.
