Modified peptizer twinned grain silver halide emulsions and processes for their preparation |
摘要 |
The present invention is directed to a process of precipitating for use in photography a silver halide emulsion employing a gelatino-peptizer containing alkylated methionine and to an emulsion produced by this process. A variety of advantages can be realized, including an increase in the population of twinned grains and a higher yield of thin tabular grains.
