PROBLEM TO BE SOLVED: To provide an original plate for a heat-sensitive lithographic printing plate to be scan exposed within a short time, mounted directly on a printer and printing without the development, provided with superior resistance to printing, free from printing stains and generating just a little contamination to an aligner and a light source. SOLUTION: An original plate for a heat-sensitive lithographic printing is provided with a three-dimensional crosslinked hydrophilic layer with a heating section to be easily removed by damping water or an ink and a water-soluble overcoating layer containing, if required, a photothermic conversion agent formed successively on a base having an ink acceptive surface or an ink acceptive layer coating it. |
