Abstract

A process for forming color images which comprises image-wise exposing a silver halide photographic material, subjecting the exposed photographic material to color development and then fixing the developed material with a fixing bath having a pH of at least 6, the process being free from a silver bleaching (elimination) step. The process is especially suitable for application to radiographic materials.
