Mesoionic silver halide stabilizer precursor and use in a heat developable and heat stabilizable photographic silver halide material and process |
摘要 |
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.
