    Abstract: A lithographic printing plate precursor includes, in the following order: a support; an image-recording layer which is capable of forming an image by removing an unexposed area of the image-recording layer with at least one of printing ink and dampening water on a printing machine after exposure and contains an infrared absorbing dye, a polymerization initiator, a polymerizable compound and a binder polymer having an alkylene oxide group; and a protective layer containing a hydrophilic polymer which contains at least a repeating unit represented by the formula (1) as defined herein, a repeating unit represented by the formula (2) as defined herein, and a repeating unit represented by the formula (4) as defined herein, and in which a content of the repeating unit represented by the formula (4) is from 0.3 to 5.0% by mole based on total repeating units of the hydrophilic polymer.

    Abstract: The invention provides a planographic printing plate precursor comprising: a hydrophilic support; and an image recording layer that is provided on the support, the image recording layer comprising: an infrared ray absorbing agent (A); a polymerization initiator (B); a polymerizable monomer (C); and a specific polymer compound (D) having an alkyleneoxy group in its molecule and having, in a side chain thereof at least one specific group. The invention further provides a printing method using the planographic printing plate precursor, wherein no specific development process is required for performing printing.
