<P>PROBLEM TO BE SOLVED: To provide a development processing solution for a lithographic printing plate, which achieves development in an acidic to neutral region and overcomes the problem of developability in the development and the problem of dispersion stability of photosensitive layer components removed by the development (development scum), and to provide a plate making method of a lithographic printing plate. <P>SOLUTION: The development processing solution for a lithographic printing plate contains a compound in which (a1) a group having a polyoxyalkylene chain, (a2) a cationic group, and (a3) an anionic group are covalently bonded in its molecule. The plate making method of a lithographic printing plate uses the processing solution. <P>COPYRIGHT: (C)2009,JPO&INPIT |
