Abstract:
A color photographic element comprising:a) a first light sensitive silver halide emulsion layer containing a tetrazole compound of Formula I that is not a coupler and does not react with oxidized developer: ##STR24##wherein when R.sub.1 is hydrogen, then R.sub.2 is an alkyl, aryl, alkoxy, aryloxy, alkylthio or arylthio, sulfoxyl, sulfonyl, sulfamoyl, --O--CO--, --O--SO.sub.2 --, a heterocyclic group, a carbonyl group or an amino group or when R.sub.2 is a thiol (--SH) group, then R.sub.1 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:COUP--(TIME).sub.j --INH IIwherein: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.
