Abstract: A bleach-fix sheet for use in color photographic processes comprises a support having thereon a bleach-fix layer and a water reservoir layer comprising a water-supplying polymer. In a preferred embodiment, the bleach-fix sheet is useful to bleach and fix a retained image in a color image diffusion transfer process.

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.

Abstract: A bleach-fix sheet for use in color photographic processes comprises a support having thereon a bleaching agent, a fixing agent and a hardened hydrophilic binder. In a preferred embodiment, the bleach-fix sheet is useful to bleach and fix a retained image in a color image diffusion transfer unit.

Abstract: Reversal color images are produced in silver halide photographic elements which employ a leuco dye comprising the reaction product of a color-forming coupler and an N,N-dialkyl-p-phenylenediamine stabilized against aerial oxidation by an electronegative group attached to the benzene ring. A method is disclosed which comprises developing a silver image in imagewise exposed areas of the silver halide element. The residual silver halide in unexposed areas is then fogged and developed while concurrently oxidizing the leuco dye in these unexposed areas to form a dye image which is a reversal of the imagewise exposure. Developed silver is then removed from the element to leave a dye image without oxidizing the leuco dye in the imagewise exposed areas of the element.

Abstract: reversal color images are produced in photographic elements which contain a ballasted primary aromatic amine and conventional ballasted color couplers. The photographic element is imagewise-exposed and a negative silver image is formed without forming a dye image. The residual silver halide in the photographic element is then fogged and developed to silver while concurrently forming a color dye image in the nonimagewise-exposed areas of the element. The developed silver is removed without removing the dye image.
