| 摘要 |
The invention provides a color photographic element comprising:a) a first light sensitive silver halide emulsion layer containing a tetrazole compound of Formula I: wherein when R1 is hydrogen, then R2 is an alkyl, aryl, alkoxy , aryloxy, alkylthio or arylthio, sulfoxyl, sulfonyl, sulfamoyl, -O-CO-, -O-SO2-, a heterocyclic group, a carbonyl group or an amino group or when R2 is a thiol (-SH) group, then R1 is an alkyl, aryl or heterocyclic group provided further that the ClogP for the compound of Formula I is at least 2.0 and less than 7.8; andb) a second light sensitive silver halide emulsion layer, having a spectral sensitivity different from that of the first light sensitive silver halide emulsion layer, containing a compound of Formula II:wherein:1) COUP is a coupler parent group capable of forming a dye upon reaction with an oxidized developer;2) TIME is a timing group bonded to the coupling position of COUP and j is 0 or 1; and3) INH is a mild silver development inhibitor fragment.The invention provides improved color reproduction.
