Patent ID: 6838233

Claim:
A photographic processing kit comprising: a) Solution A comprising at least 0.5 mol/l of a photographic fixing agent, and b) Solution B comprising at least 0.1 mol/l of a ferric-ligand photographic bleaching agent, and either or both of Solutions A and B comprising at least 0.05 mmol/l of a sulfur-containing compound represented by one or more of the following Structures I, II, III, IVb, and V: wherein Q 1 represents a group of atoms that are necessary to complete a nitrogen-containing heterocyclic ring, and R 1 represents hydrogen, or an alkyl, cycloalkyl, aryl, heterocyclic, or amino group, wherein Q 2 represents a group of atoms that are necessary to complete a nitrogen-containing heterocyclic ring, and R 2 represents hydrogen, an alkali metal atom, a group wherein Q 3 is defined the same as Q 2 , or an alkyl group, wherein R 3 and R 4 are independently alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl, or heterocyclic groups, or R 4 can be hydrogen, and Y is —O—, —S—, or —N(R5)— wherein R 5 is an alkyl, cycloalkyl, alkenyl, alkynyl, aryl, heterocyclic, amino, acylamino, sulfonamido, ureido, or sulfamoylamino group, or R 3 and R 4 , or R 4 and R 5 , taken together, independently, any form a heterocyclic ring, wherein R 6 , R 7 , and R 8 independently represent hydrogen, alkali metal ions, or alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl, heterocyclic, amino, acylamino, ureido, or sulfamoylamino groups, and wherein R 9 , R 10 , R 11 and R 12 independently represent hydrogen, alkali metal ions, or alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl, heterocyclic, amino, acylamino, ureido, or sulfamoylamino groups, and R 13 represents an alkyl, cycloalkyl, alkenyl, alkynyl, aralkyl, aryl, heterocyclic, amino, acylamino, ureido, or sulfamoylamino group.
