Abstract
The planographic printing plate precursor according to the present invention includes: a support; and a photosensitive layer provided on the support and containing a polymer having the structural unit represented by the following Formula (1) and an acid coloring colorant represented by the following Formula (2). The planographic printing plate precursor is superior in each of chemical resistance, solubilization discrimination, and image reproducibility. In Formula (1) above, X represents a bivalent connected group; Rrepresents an alkyl or aryl group; and x is 0 or 1. In Formula (2) above, rings A, B and C each independently represent a mono- to tri-nuclear aromatic hydrocarbon group or a heterocyclic aromatic group; at least one of the rings B and C is substituted with at least one substituent group selected from the group consisting of amino, alkoxy, aryloxy, alkylthio, and arylthio groups; the rings B and C may bind to each other via a binding group; Wrepresents a carbonyl group, a thiocarbonyl group, or, —C(R)═N—, wherein Rrepresents a hydrogen atom or a hydrocarbon group, and Qrepresents an oxygen or sulfur atom, or an imino group; Rto Reach independently represents a hydrogen atom or a hydrocarbon group; and m and n are each independently 0 or 1.
