Stable free radical nitroxyl bleaching agents for photographic processes |
摘要 |
Disclosed herein are aqueous and nonaqueous photographic bleaching solutions and photothermographic elements comprising stable free radical nitroxyl bleaching agents. These agents are capable of bleaching preformed of developed metals, such as silver, in both aqueous and nonaqueous photographic materials. They do not adversely affect the photographic properties of radiation sensitive emulsions and can be thermally activated in a dry photothermographic process.
