| titleOfInvention | One-part bleach-fix liquid concentrates |
| abstract | Compositions and methods of making photographic one-part bleach-fix liquid concentrates, packaged in a single unit, wherein the bleaching agent is a polyvalent metal oxidizing agent are described. A thiocyanate salt is added in an amount sufficient to provide one-part bleach-fix liquid concentrates that are homogeneous, remain free of crystallized precipitates for extended periods of time, and that retain effective oxidizing potential during extended periods of storage. Alternatively, the present invention provides for compositions and methods of making stable bleach-fix liquid concentrates, suitable for dilution to working strength solutions, using a polyvalent metal oxidizing bleaching agent, at least one fixing agent, and a source of phosphate ions. Precipitation, which occurs when an iron (III) bleaching agent is reduced by components of the concentrate, is prevented by the addition of thiocyanate and/or phosphate ions. If phosphoric acid is used as the source of phosphate ions, it will prevent the occurrence of precipitates and maintain the acidity of the concentrate. If desired, any phosphate salt may be used as a source of phosphate ions. |
