ABSTRACT:
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.
