发明名称 Color photographic element containing nitrogen heterocycle derivative and inhibitor releasing coupler
摘要 Disclosed is a color photographic element comprising: a) a first light sensitive silver halide emulsion layer containing a compound with an aromatic bicyclic nitrogen nucleus of which at least one ring is six-membered and with two nitrogen ring atoms in each ring and with at least one N-H bond provided that the ClogP for the compound is at least 2.0 and less than 7.2; and (b) 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 III: COUP-(TIME)j-INH wherein: COUP is a coupler parent group capable of forming a dye upon reaction with an oxidized developer; TIME is a timing group and j is 0,1 or 2; and INH is a mild silver development inhibitor fragment. The invention provides improved color reproduction.
