ABSTRACT:
A heat developable photographic material for producing a dye enhanced silver image comprising, in binder, in reactive association, (a) photosensitive silver halide, (b) a dye-forming coupler, (c) an oxidation-reduction image-forming combination comprising (i) a 3-amino-1H-1,2,4-triazole silver salt oxidizing agent, with (ii) an organic reducing agent which in its oxidized form forms a dye with the dye-forming coupler, and (d) an antifoggant concentration of a 5-mercapto-1,2,4-triazole antifoggant, provides developed, dye enhanced silver images with reduced fog upon processing. An image can be developed in this photographic material by merely heating the material. Other addenda employed in heat developable photographic materials, such as sensitizing dyes, can be useful with the described photographic materials.
