    摘要: A lithographic printing process which comprises the steps of: imagewise exposing to infrared light a presensitized lithographic plate which comprises a hydrophilic support and a removable image-forming layer containing an infrared absorbing agent having the absorption maximum within an infrared region and a dye precursor having substantially no absorption within a visible region to change the dye precursor to a visible dye having an absorption within a visible region within the exposed area, and to make the image-forming layer irremovable within the exposed area; removing the image-forming layer within the unexposed area of the lithographic plate mounted on a cylinder of a printing press; and then printing an image with the lithographic plate mounted on the cylinder of the printing press. The other processes are also disclosed.

    摘要: A lithographic printing plate precursor comprising: a support; and at least one layer comprising an image-recording layer, the image-recording layer comprising (A) an infrared absorber, (B) a polymerization initiator, (C) a polymerizable compound, and (D) a binder polymer, wherein the image recording layer is capable of being removed with at least one of a printing ink and a fountain solution, wherein at least one of said at least one layer comprises a copolymer having (a1) a unit comprising at least one ethylenically unsaturated bond, and (a2) a unit comprising at least one functional group interacting with a surface of the support. And a lithographic printing method in which the lithographic printing plate precursor is used. The copolymer preferably has a hydrophilic segment. The copolymer preferably is contained in an undercoat layer formed between the support and the image-recording layer.
