ABSTRACT:
A process of developing exposed silver halide elements comprises developing said element in a developer in the presence of a development accelerator compound as defined. The development accelerator compounds include pyridinium, or pyridinium and and imidazolium compounds. The process is applicable to standard and hydrazine-containing films and to hydroquinone and/or ascorbic acid-based developers. The development accelerator may be incorporated into the developer or into the silver halide emulsion.
