Abstract

The present invention offers a silver halide photographic light-sensitive material which is excellent in dye image storage stability, which undergoes little change in the photographic performance thereof between initiation and completion of continuous processing, which has excellent color reproducibility and sufficient color developability. The present invention comprises a silver halide photographic light-sensitive material having at least one silver halide emulsion layer containing a dye-forming coupler on the support, wherein said silver halide emulsion layer contains at least one compound having an ester group and an oxidation potential of not more than 1800 mV.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A silver halide light-sensitive photographic material comprising a support having provided thereon, a silver halide emulsion layer containing a compound represented by Formula II, and a cyan coupler represented by Formula C-I or CII; ##STR186## wherein R 21  and R 22  independently represent hydrogen or alkyl having 1 to 5 carbon atoms; J represents alkylene or a simple bond; R 23  represents a heterocyclic residue; ##STR187## wherein R C1  represents alkyl having 2 to 6 carbon atoms; R c2  represents a ballast group; Z c  represents hydrogen or a group capable of splitting off upon coupling with the oxidation product of a developing agent, ##STR188## wherein R c1  represents alkyl, cycloalkyl, aryl or a heterocyclic group; R c2  represents a ballast group; R c3  represents hydrogen, halogen, alkyl or alkoxy; R c1  and R c3   may combine to form a ring; Z c  represents hydrogen or an atom or group capable of splitting off upon coupling with the oxidation product of a developing agent. 
     
     
       2. A silver halide light-sensitive photographic material comprising a support having provided thereon, a plurality of silver halide emulsion layers including at least a first silver halide emulsion layer containing a compound represented by Formula II, and a yellow coupler represented by Formula Y-I; and a second silver halide emulsion layer containing a cyan coupler represented by Formula C-I or C-II, and a compound of Formula II; ##STR189## wherein R 21  and R 22  independently represent hydrogen or alkyl having 1 to 5 carbon atoms; J represents alkylene or a simple bond; R 23  represents a heterocyclic residue; ##STR190## wherein R 1  represents alkyl or cycloalkyl; R 2  represents alkyl, cycloalkyl, aryl or acyl; R 3  represents a group capable of being a substituent on a benzene ring; n represents 0 or 1; X 1  represents a group capable of splitting off upon coupling with the oxidation product of a developing agent; Y 1  represents an organic group; ##STR191## wherein R c1  represents alkyl having 2 to 6 carbon atoms; R c2  represents a ballast group; Z c  represents hydrogen or a group capable of splitting off upon coupling with the oxidation product of a developing agent, ##STR192## wherein R c1  represents alkyl, cycloalkyl, aryl or a heterocyclic group; R c2  represents a ballast group; R c3  represents hydrogen, halogen, alkyl or alkoxy; R c1  and R c3  may combine to form a ring; Z c  represents hydrogen or an atom or group capable of splitting off upon coupling with the oxidation product of a developing agent.
