ABSTRACT:
In a heat developable photographic material and process for providing a dye enhanced silver image, an element comprising a support having thereon in reactive association: (A) at least one heat developable photographic layer comprising (i) photosensitive silver halide, (ii) at least one active silver halide developing agent, (iii) an activating concentration of a development activator precursor, and (iv) a polymeric binder and (B) at least one layer comprising an azoaniline dye that is bleached in the non-image areas of the described element upon development of a latent image in the layer (A) by uniformly heating, can provide an improved image. After imagewise exposure of the described heat developable material, a dye enhanced silver image can be provided by heating the element containing the described combination of layers and materials.
