Abstract
Mesoionic 1,2,4-triazolium-3-thiolates are silver halide stabilizers and fixing agents. They are useful in heat developable and heat stabilizable photographic silver halide materials and processes. After imagewise exposure of the photographic materials, developed and stabilized silver images are produced by heating the materials. The mesoionic 1,2,4-triazolium-3-thiolates are also silver halide stabilizers and fixing agents in photographic silver halide processing compositions.
