PHOTOGRAPHIC SILVER CHLORIDE EMULSIONS

摘要

A photosensitive silver chloride emulsion comprising at least 90 % silver chloride whose keeping properties have been improved by the incorporation therein of a bisphenol derivative having two linked phenol rings wherein the hydrogen atom of one of the phenolic hydroxy groups is replaced by a blocking group which is a substituent other than hydrogen and at least one of the phenol rings is substituted.
