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.

Abstract: Novel photographic products for use in color diffusion transfer systems employing a neutralizing layer for lowering the environmental pH after application of an aqueous alkaline processing fluid and a ''''timing'''' or 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 essence of the invention being employing as the spacer layer comprising, as a continuous phase, the coalesced essence of an aqueous filmforming synthetic polymer dispersion which is substantially impermeable to the processing fluid and a discontinuous phase consisting essentially of polyvinyl alcohol.
