| titleOfInvention |
Photographic silver halide emulsions with improved bright room tolerance |
| abstract |
A photographic silver halide emulsion comprising silver halide grains having a chloride content of at least 90 mole percent and a rhodium salt, wherein said grains have been sensitized with a black and white developing agent, provides a substantial improvement in bright room tolerance as compared to emulsions sensitized with more conventional sensitizing agents, without loss of speed or contrast. A process for improving the bright room tolerance of a photographic emulsion comprising silver halide grains having a chloride content of at least 90 mole percent and a rhodium salt comprises the step of sensitizing the grains with a black and white developing agent. |
