Abstract (en)

[origin: EP3002124A1] An object of the present invention is to provide a lithographic printing plate precursor that has excellent printing durability and developability and that has stain resistance, in particular resistance to staining of a non-image area of a printed material that occurs due to the operation of a slip mechanism of a dampener, and a process for making a lithographic printing plate using the lithographic printing plate precursor. Disclosed is a lithographic printing plate precursor comprising, in order above a support, an intermediate layer and an image recording layer, the intermediate layer comprising, as Component A, a specific copolymer, the image recording layer comprising an infrared absorbing agent, either the intermediate layer or the image recording layer comprising, as Component B, a specific polymer compound, and the mass ratio of Component A and Component B being Component A:Component B = 1:0.5 to 1:5.
