Process for preparing high chloride (100) tabular grain emulsions |
摘要 |
A process of preparing a photographically useful high chloride {100} tabular grain emulsion is disclosed that, following grain nucleation, introduces the total silver required for grain growth before undertaking ripening at a temperature of from 60 to 95 DEG C. The advantages attainable include a higher concentration of the silver in the final emulsion and high chloride tabular grains having larger mean grain sizes and higher average aspect ratios and accounting for a higher percentage of total grain projected area.
