PROBLEM TO BE SOLVED: To manufacture a waterless lithographic printing original plate of superior resistance to scuffing, superior resistance to solvent and good image productivity, on which laser drawing can be performed. SOLUTION: A waterless lithographic printing original plate is formed of a photothermal conversion layer containing a compound converting laser beams into heat and a silicone rubber layer laminated together in the above order on a substrate, and the photothermal conversion layer contains a reactive material of a metal chelate compound such as a titanium diisopropoxide bis(2,4- pentadionate) and/or a self-condensation material of the metal chelate compound. The photothermal conversion layer contains a polymer containing active hydrogen in molecules. |
