    Abstract: The present invention provides method for preparing a lithographic printing plate comprising: (i) exposing to laser light having a wavelength of 350-450 nm a lithographic printing plate precursor comprising a hydrophilic support; a photosensitive layer containing (A) a sensitising dye having a maximum absorption wavelength of 350-450 nm, (B) a hexaarylbiimidazole compound, (C) a polymerizable compound, (D) a hydrophobic binder polymer having a crosslinkable functional group in a side chain, and (E) a chain transfer agent; and a protective layer in this order; and (ii) rubbing a surface of the exposed lithographic printing plate precursor with a rubbing member in an automatic processor in the presence of a developer having a pH of 2-10 to remove the protective layer and unexposed areas of the photosensitive layer. A lithographic printing plate precursor as defined above is also provided, wherein the hydrophobic binder polymer has an acid value of 0.3 meq/g or less.

    Abstract: A lithographic printing process comprises the steps of: imagewise exposing to infrared light a presensitized lithographic plate which comprises a hydrophilic support and an image-forming layer containing an infrared absorbing agent, a polymerization initiator and a binder polymer to polymerize the polymerizable compound within the exposed area; removing the image-forming layer within the unexposed area while mounting the lithographic plate on a cylinder of a printing press; and then printing with the lithographic plate while mounting the lithographic plate on the cylinder of the printing press. The polymerization initiator is a salt of an anion with a sulfonium ion. According to the present invention, a specific anion or a specific sulfonium ion is used in the polymerization initiator.
