Abstract
Photographic assemblages, elements, receiving elements and cover sheets comprise a combination of two timing layers and a neutralizing layer. The outermost timing layer contains photographic addenda, such as development inhibitors, for substantially terminating development of the silver halide emulsion. The timing layer next to the neutralizing layer has a much longer breakdown time so that it is permeated by the alkaline processing composition only after silver halide development has been substantially terminated.
