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.
Claims4
A cover sheet adapted to be permeated by an alkaline processing composition, comprising a transparent support having thereon, in sequence, a neutralizing layer for neutralizing said alkaline processing composition, a second timing layer and a first timing layer, said first timing layer being capable of being permeated by said alkaline processing composition in a relatively short time and containing photographic addenda for substantially terminating development of a silver halide emulsion layer, and said second timing layer being capable of being permeated by said alkaline processing composition only after said silver halide development has been substantially terminated.
