    (54) Bleach-fixing solution having good processing performance and method for processing light-sensitive material using the same


    (57) Disclosed is a bleach-fixing solution comprising a processing solution for bleach-fixing a light-sensitive silver halide photographic material for photographing, wherein said solution has the pH ranging between 3.0 and 6.8. contains a ferric complex salt having a ligand comprising a compound represented by General Formula (I), and further contain at least one of;

    i) at least one compound selected from the compounds represented respecytively by General Formula (II) and General Formula (III);

    ii) a polymer having a unit of pyrrolidone nucleus in the molecular structure; and iii) a ferric complex salt having a ligand comprising at least one compound selected from the compounds represented respectively by General Formulas (IV) to (VII). The General Formulas (I) to (VII) are described in the specification.

    Disclosed is also a method for processing a light-sensitive material by using the bleach-fixing solution.


    By use of the bleach-fixing solution of this invention, rapid processing of the light-sensitive material is enabled without a generation of ammonia gas, because the bleach-fixing solution can delay the occurence of the precipitation even during storage with time to attain a stable bleach-fixing performance, and it can improve the bleach stain at a non-image portion of a light-sensitive material when the processing with low replenishment is carried out.
