    Abstract: Novel photographic products for use in color diffusion transfer, particularly color diffusion transfer systems for forming color images viewable without separation as reflection prints, which products include a neutralizing layer for lowering the environmental pH after application of an aqueous alkaline processing fluid and a ''''timing'''' spacer layer so disposed with respect to the neutralizing layer that the processing fluid must first diffuse through the spacer layer before contacting the neutralizing layer, the spacer layer comprising, as a continuous phase, the coalesced essence of an aqueous film-forming synthetic polymer dispersion which is substantially impermeable to the processing fluid and a discontinuous phase comprising a material which is permeable to the processing fluid.

    Abstract: THIS INVENTION IS DIRECTED TO MICROSCOPIC CAPSULES COMPRISING A CONTINUOUS SYNTHITIC POLYMERIC LAYER SURROUNDING A NUCLEUS COMPOSED OF PHOTOSENSTIVE SILVER HALIDE GRAINS WHEREIN THE POLYMERIC LAYER IS OF SUFFICIENT THICKNESS TO SUTSTANTIALLY OVERCOME THE ATTRACTIVE FORCES OF SAID SILVER HALIDE GRAINS FOR ADJACENT SILVER HALIDE GRAINS. THUS, THE PRESENT INVENTION COMTEPLATES INDIVIDUAL GRAINS OF PHOTOSENSITIVE SILVER HALIDE WHICH ARE SPATIALLY SEPARATED FROM ADJACENT GRAINS BY MEANS OF A POLYMERIC LAYER ENCASING THE GRAINS. THE PRESENT INVENTION IS ALSO DIRECT TO METHODS FOR PROVIDING SUCH ENCAPSULATED PRODUCTS AND TO PHOTOGRAPHIC PRODUCTS EMPLOYING SAID CAPSULES.

    Abstract: Novel photographic products for use in diffusion transfer systems for forming visible images, particularly systems for forming color images viewable, without separation as color reflection prints, which products include a neutralizing layer for lowering the environmental pH after application of an aqueous alkaline processing fluid, the neutralizing layer comprising a water-soluble acidic compound and a hydrophobic reagent obtained from a water-soluble precursor contained in the aqueous coating solution employed to prepare the neutralizing layer.
