<p>A [S,S]-alkylenediamine-N,N'-disuccinic acid or its salt is added into a mixing tank to form a solution. Subsequently, ferric salt(s) chosen from ferric nitrate, ferric chloride, ferric bromide and ferric sulfate, is added with stirring to form a kit part of bleach-fixing solution. A [S,S]-alkylenediamine-N,N'- disuccinic acid or its salt is added into a mixing tank to form a solution. Subsequently, ferric salt(s) is added to the mixing tank with stirring to form a kit part of bleach-fixing solution. The ferric salt is chosen from ferric nitrate, ferric chloride, ferric bromide, ferric sulfates of formulae (M1)3Fe(III)(SO4)3 and (M1)Fe(III)(SO4)2, where M1 is hydrogen, sodium, potassium or ammonium. Independent claims are included for the following: (1) preparation of kit of bleaching solution for photographic materials; and (2) processing of silver halide color photographic material which involves exposing photographic material to light, color developing exposed photographic material and subjecting the developed photographic material to bleach-fixing or bleaching with a bleach-fixing solution or bleaching solution, respectively. The bleach-fixing and bleaching solutions are prepared using above prepared kit part or kit of bleaching solution.</p> |
