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.
