ON-PRESS DEVELOPMENT TYPE LITHOGRAPHIC PRINTING PLATE PRECURSOR, METHOD OF PRODUCING LITHOGRAPHIC PRINTING PLATE, AND LITHOGRAPHIC PRINTING METHOD

摘要

Provided are: an on-press development type lithographic printing plate precursor which has, in order, a support, an image recording layer, and an overcoat layer, wherein the image recording layer includes a binder polymer and an electron donor type polymerization initiator, the binder polymer has a constituent unit formed by an aromatic vinyl compound and a constituent unit formed by an acrylonitrile compound, and the overcoat layer has a thickness that is greater than the thickness of the image recording layer; a method of producing a lithographic printing plate using the on-press development type lithographic printing plate precursor; and a lithographic printing method using the on-press development type lithographic printing plate precursor.
