392104 MESOIONIC SILVER HALIDE STABILIZER PRECURSOR AND USE IN A HEAT DEVELOPABLE AND HEAT STABILIZABLE PHOTOGRAPHIC SILVER HALIDE MATERIAL AND PROCESS Mesoionic 1,2,4-triazolium-3-thiolate silver halide stabilizer precursors are novel compounds useful in a heat developable and heat stabilizable photographic silver halide materials and processes. After imagewise exposure of the photographic material, a developed and stabilized silver image is produced by heating the element. Mesoionic stabilizer precursors are also useful in photographic silver halide processing compositions.
