ABSTRACT:
A scavenger-spreader element adapted for use with a photosensitive element to form a negative image is disclosed as well as methods for processing said photosensitive element to produce the negative image. The scavenger-spreader element comprises a support carrying a hydrophilic layer, a cross-linking agent for the polymeric thickener of the photographic processing composition, a barrier layer to control diffusion of said cross-linking agent and a layer adapted to possess substantial adhesion for the cross-linked polymeric thickening agent.
