ABSTRACT:
A lithographic printing plate is prepared from a silver halide photosensitive material in accordance with a silver complex diffusion transfer process. The photosensitive material is exposed and developed with a diffusion transfer processing solution containing a mesoionic compound as a silver halide complexing agent. The printing plate has good ink receptivity and minimized plate wear. The processing solution is free from the problems of corrosion and waste solution disposal.
