<P>PROBLEM TO BE SOLVED: To provide a development processing solution for a lithographic printing plate which allows development in an acidic to neutral region and overcomes the problems of developability and dispersion stability of photosensitive layer components removed by development (development scum), and a plate-making method of a lithographic printing plate. <P>SOLUTION: The plate-making method of a lithographic printing plate includes: exposing imagewise a lithographic printing plate precursor including an image-recording layer containing a binder polymer on a support to cure an exposed area of the image-recording layer; and developing the exposed lithographic printing plate precursor with a development processing solution having pH of 2.0-8.0, wherein the binder polymer has a structure including at least one of an amino group and an ammonium group, and the development processing solution contains at least one surfactant containing a nitrogen atom. <P>COPYRIGHT: (C)2009,JPO&INPIT |
