ABSTRACT:
Lithographic printing plates having high ink receptivity, suffuring no ink stains and having much improved printing endurance can be produced by silver complex diffusion transfer process from lithographic printing plate materials comprising a support having thereon at least both silver halide emulsion layer and physical development nuclei layer wherein the diffusion transfer processing is carried out in the presence of 2-mercaptobenzoic acid derivatives or, besides this 2-mercaptobenzoic acid derivatives, at least one compound selected from the group consisting of alkanolamines and cyclic imide compounds which may be contained in at least one layers of the lithographic printing plate materials and/or the diffusion transfer developing solutions.
