<P>PROBLEM TO BE SOLVED: To provide an original plate for a lithographic printing plate which can be supplied for printing as it is without developing after scanning exposure based on a digital signal and has an enhanced plate wear and to provide a method for platemaking and printing using the same. <P>SOLUTION: The original plate for the lithographic printing plate includes an image forming layer containing (1) a microcapsule for containing fine particles for containing a compound having two or more functional groups crosslinkable by an acid and/or a compound having two or more functional groups crosslinkable by an acid (acid crosslinking component), (2) a microcapsule for containing fine particles for containing a compound having two or more functional groups polymerizable by a radical and/or a compound having two or more functional groups polymerizable by a radical (radical polymerizing component), (3) a photothermal converging agent, (4) a thermosensitive acid generating agent, and (5) an image forming layer containing the thermosensitive radical generating agent on a support. The original for this lithographic printing plate is developed in a machine after an exposure with an infrared laser beam, and is served for printing. <P>COPYRIGHT: (C)2004,JPO |
