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.
