Abstract
1340131 Photographic silver halide bleachfix composition EASTMAN KODAK CO 19 April 1971 [23 March 1970] 24555/71 Heading G2C An aqueous photographic bleach-fix solution comprises (A) 0À4 to 2À0 moles/litre of a watersoluble silver bleaching agent having an alkali metal, ammonium or amine cation and an anion comprising Fe (III) complexed with a polyfunctional ligand, (B) a water-soluble secondary ligand selected from a thiocyanate, borate, boric acid, fluoride or thiourea, the molar ratio of the thiocyanate to (A) being at least 5: 1, the molar ratio of borate, boric acid or fluoride to (A) being at least 1: 1 and the molar ratio of thiourea to (A) being at least 3: 1 and (C) if not already completely provided by (B), a water-soluble silver halide fixing agent in an amount of up to 1-5 moles/litre. The solution may have a pH of 5 to 9. The secondary ligand (B) may be a thiourea of the formula:- R<SP>11</SP> R<SP>10</SP> N-CS-N R<SP>8</SP>R<SP>9</SP> wherein R<SP>8</SP> and R<SP>11</SP> are each H, methyl or hydroxyethyl; R<SP>9</SP> and R<SP>10</SP> are each H, methyl, hydroxyethyl, NH 2 , NHCH 3, N(CH 3 ) 2 , NHCH 2 CH 2 OH, N(CH 2 CH 2 OH) 2 or N(CH 3 ) CH 2 CH 2 OH, the thiourea containing at least one NH group. The fixing agent (C) may be a water-soluble thiosulphate, thiocyanate, a thiourea or a thioether. The polyfunctional ligand (A) may be ethylenediamine tetraacetic acid or N-(#-hydroxyethyl) ethylenediamine triacetic acid, and many others are listed. Concentrated solutions can be made which are useful for storage and with materials having a high silver content. The secondary ligands (B) replace the watermolecule in the ferric complex (A) and prevent dimensation throughout the pH range 4 to 9.
