Abstract: The invention provides an OLED device including an anode, a cathode and a green light-emitting layer located therebetween, said light-emitting layer including an anthracene host, a bis-diarylamine 9,10-substituted anthracene and a stabilizer compound which is selected from a quinacridone or a biphenylstyrylamine. Devices of the invention provide improvement in features such as stability and efficiency while maintaining excellent color.

Abstract: The invention provides a color photographic element comprising: a) a first light sensitive silver halide emulsion layer containing a compound of Formula 1:  wherein: M is hydrogen, an alkali metal cation or an ammonium cation, X is oxygen, sulfur or selenium, and Q represents a ballasting moiety; provided further that the ClogP for the compound of Formula I is at least 1.0 and less than 7.6; 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 II: COUP—(TIME)j—INH  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 and j is 0 or 1; and 3) INH is a mild silver development inhibitor fragment. The invention provides improved color reproduction.

Abstract: Disclosed is a photographic element comprising a non-light sensitive layer containing elemental silver and a heterocyclic thiol compound having a Clog P of at least 2.0 but less than 12.0, provided that the ring system of the compound comprises a --N.dbd.C--S--H group or its tautomer and does not react with an oxidized developer. The invention provides improved minimum densities in imaging layers.

Abstract: There are described reversal photographic elements containing magenta dye-forming couplers that yield dye images that particularly lend themselves to retouching. The photographic element comprises a pyrazoloazole magenta dye forming coupler having a cleavable ballast group joined to the remainder of the molecule by one or two electrophilic cleavage groups which can be removed with a specialized processing composition after reversal processing.
