Studies on the Photographic Stabilizers. II

Relationship between Photographic Effects and Silver Potentials

Abstract

Silver potential titration was carried out on compounds used for emulsion tests and relationship between potential and photographic properties was examined. In general, the loss noble the potential, the stronger became stabilization action, but too base a potential was found to be accompanied with side effects, such as desensitization on addition, and good stabilizers were found to have medium potential. If the reaction product of the compound and silver ion was to be taken as a sparingly soluble silver salt, it was concluded that good stabilizers would not form a silver salt in photographic emulsion in the amount added.
