Silver complex diffusion transfer processing

摘要

A method for the production of a photographic image by silver complex diffusion transfer processing wherein a negative working silver halide emulsion material having particularly high exposure latitude and being manipulatable under room light conditions without prohibitive fogging is used, said material having a low intensity reciprocity failure (L.I.R.F). The material is contact-exposed with visible light through a sheet support carrying paper paste-up material with its information facing the silver halide emulsion layer of the photographic material, and the resulting latent image is developed in the presence of a silver halide complexing agent and the thus developed silver halide emulsion material is contacted with an image-receiving material to form according to a preferred embodiment a planographic printing plate.
