A lithographic printing plate precursor which is excellent in both the on-press development property and the printing durability and which is excellent particularly in the on-press development property after preservation for a long period of time, wherein the lithographic printing plate precursor includes an intermediate layer containing a polymer compound including a repeating unit (a1) having a support-adsorbing group and a repeating unit (a2) having a polyoxyalkylene group having a repeating number of oxyalkylene units from 8 to 120 between a support and a polymerizable image-recording layer, and contains a compound having a molecular weight of 1,500 or less and having an oxyalkylene group in at least any of the intermediate layer and the polymerizable image-recording layer.

Lithographic printing plate precursor and plate making method thereof

A lithographic printing plate precursor includes: a support; and an image-recording layer containing (A) a polymerization initiator, (B) a sensitizing dye and (C) a polymerizable compound, and the image-recording layer or an undercoat layer which is optionally provided between the support and the image-recording layer comprises (D) a polymer compound comprising (a1) a repeating unit having a side chain having a structure represented by the following formula (a1-1) and (a2) a repeating unit having a side chain having at least one structure of the formulae (a2-1), (a2-2), (a2-3), (a2-4), (a2-5) and (a2-6) as defined herein.

Lithographic printing plate precursor, plate making method thereof and novel polymer compound
