US 7,135,275 B2 · Solid bleach-fixing composition for silver halide color photographic light-sensitive material, and method for processing silver halide color photographic light-sensitive material

Abstract

A solid bleach-fixing composition for a silver halide color photographic light-sensitive material, comprising at least one specific 5-membered heterocyclic azoliumthiolate compound, particularly, a solid bleach-fixing composition wherein the specific thiolate compound is a diazolium-thiolate compound substituted by a water-soluble group. A method for processing a silver halide color photographic light-sensitive material, comprising using a bleach-fixing solution containing a specific 5-membered heterocyclic azoliumthiolate compound, and regenerating at least 50 mass % of the used bleach-fixing solution as a bleach-fixing processing agent for replenishment; and a method for processing a silver halide color photographic light-sensitive material, comprising regenerating at least 30 mass % of the used processing solution further containing used rinsing solution as a bleach-fixing processing agent for replenishment.

Dependent claims

A solid bleach-fixing composition for a silver halide color photographic light-sensitive material, comprising at least one compound represented by formula (Ia):

wherein Y′ represents N—R6 or NNR7R8;
and R6, R7, R8, R9 and R10 are the same or different and each represents a substituted or unsubstituted alkyl group having from 1 to 6 carbon atoms, provided that R7, R8 and R9 each may be a hydrogen atom and that at least one of R6, R7, R8, R9 and R10 is substituted by at least one carboxylic acid group or sulfonic acid group,
and further comprising a silver complex salt of said at least one compound represented by formula (Ia).

Dependencies are inferred from the claim text.
