Trockenflachdruckplatte-Vorstufe sowie Verfahren zu ihrer Herstellung

摘要

The present invention is a waterless planographic printing plate precursor on which laser writing is possible, which has excellent scratch resistance and solvent resistance, and which also has excellent image reproducibility. The waterless planographic printing plate precursor comprises a substrate on which are superposed in the following order a light-to-heat conversion layer containing a compound for converting laser light to heat, and a silicone rubber layer, wherein the light-to-heat conversion layer contains a reaction product of a metallic chelate compound such as titanium diisopropoxide bis (2, 4-pentadionate) and/or a self-condensation product of a metallic chelate compound.
