ABSTRACT:
A process for developing a photographic material containing on a support an image-wise exposed silver halide emulsion layer of which the silver halide is substantially silver chloride and in which the photographic material before its exposure contains already at least one silver halide developing agent in a hydrophilic colloid binder in waterpermeable relationship with the silver halide, said process containing the step of contacting the exposed photographic material with an aqueous alkaline liquid, called activator liquid, being initially substantially free from developing agent(s), said contacting being not followed by a silver complex diffusion transfer processing, characterized in that said aqueous alkaline liquid contains a primary and/or secondary amine.
