摘要： A photographic element for processing in moderate to large volume photofinishing baths and comprising one and only one dimensionally stable coating support, and coated thereon in reactive association an imaging layer containing radiation sensitive silver halide, a diffusible-dye forming layer containing a diffusible-dye forming compound, and a barrier layer overlaying said diffusible-dye forming layer is disclosed. This coating support is selected from reflection base and transparent base materials, and this diffusible-dye forming layer may be the same or different than this imaging layer. This barrier layer contains a polymer that allows the passage of solutions for processing when this element is contacted with an external processing bath, and impedes the diffusion out of this element of the diffusible dye formed from this diffusible-dye forming compound.

摘要： The invention is accomplished by providing an aqueous dispersion of a photographic coupler by precipitation from a solvent solution by solvent and/or pH shift. A second aqueous dispersion of an activating permanent solvent for the photographic coupler is also provided. The dispersion of activating permanent solvent and photographic coupler are combined to form a combined dispersion which is mixed with a gelatin dispersion of silver halide particles to form a photographic emulsion suitable for casting as a photographic element. In a preferred method of the invention, the activating solvent is incorporated into a dispersion of latex particles prior to being combined with the dispersion of photographic coupler.
