<P>PROBLEM TO BE SOLVED: To provide a lithographic printing plate having sufficient sensitivity and high plate wear and using a silver complex salt diffusion transfer method. <P>SOLUTION: The lithographic printing plate has a photosensitive surface comprising at least a base coating layer, a silver halide emulsion layer and a physical developing nuclei layer successively applied on a supporting body and has a back coating layer on the other face of the supporting body, and uses a silver complex diffusion transfer method. In the plate, the back coating layer contains mercapto triazole, mercapto tetrazole or derivatives of these. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
