Fixer additives used in combination with iron complex based bleaches to improve desilvering |
| abstract |
A method of treating a seasoned fixing solution comprising desilvering a fixing solution containing a chelating compound represented by Formula I n n n n MOOC(CH₂) m (X) p ((CH₂) n COOM) q (I) n n n n where X is N, or C-OH; n n and m are independently 0, 1, or 2; n if X is N then p is 0 or 1 and q is 1 or 2; n if X is C-OH then p is 0, 1 or 2 and q is n 1 or 2; and n M is a cationic counterion; and nfurther containing a carryover amount of a bleaching agent which is a complex of ferric ion and a tridentate or a tetradentate ligand. |
