Abstract (en)

[origin: WO0150196A1] 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 phosphate ions.
