摘要： The invention provides a photographic element comprising a support bearing at least one silver halide emulsion layer and associated therewith (a) at least one coupler capable of releasing a development accelerator on colour development (DARC) and (b) at least one electron transfer agent-releasing coupler (ETARC), the DARC having the formula (I):- COUP-(T)n-X (I) wherein COUP is a coupler moiety; T is a timing group and n is 0, 1 or 2; and X is A-(L)1- -(Y)S-NR 1 NR2-CO-CO-R 3 ; wherein A is a group capable of being adsorbed to the silver halide surface; L is a divalent linking group and r is 0, 1 or 2; Y is selected from the class consisting of an unsubstituted or substituted aryl or heterocyclic ring or ring system containing one or more O, N or S atoms and s is 0 or 1; R 1 and R 2 are independently selected from the class consisting of hydrogen, an unsubstituted or substituted acyl or alkyl- or aryl-sulfonyl group; and R 3 is selected from the class consisting of R, OR, NHR and NRR1; wherein R and R1 are independently selected from the class consisting of an unsubstituted or substituted alkyl, aryl or heterocyclic ring or ring system containing one or more O, N or S atoms; provided that (a) when s is 0, r is 0 and (b) the log Kow of XH is at least 3. The elements comprising the novel DARC(s) maintain the known synergistic speed improvement when combined with an ETARC(s), without however the high D min penalty.

摘要： A silver halide color photosensitive material having a high photosensitivity, undergoing little fog, excellent in granularity, and having a good stability of reproduction of skin-color gradation. The silver halide color photosensitive material is characterized in that the material has a support, nonphotosensitive layers and red-, green-, and blue-photosensitive layer units, each photosensitive layer being composed of two photosensitive layers, the nonphotosensitive layers being interposed between the red-photosensitive maximum photosensitive layer and the green-photosensitive minimum photosensitive layer, and all layers being formed over the support; the amount of silver applied to the red-photosensitive maximum photosensitivity layer is 0.1 to 1.0 g/cm ; the red-photosensitive maximum photosensitivity layer contains a non-diffusable DIR compound; the green-photosensitive minimum sensitivity layer contains a diffusable DIR compound; at least one of the nonphotosensitive layers contains an oxidation inhibitor having a specific structure.
