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.
