    摘要： A hologram recording material is provided and has at least a silver halide, an organic refractive index-modulating agent, and a binder. The silver halide undergoes sensitization in accordance with interference fringes caused by holographic exposure, to thus form a latent image. Thereafter the silver halide is subjected to a development process to thus develop the thus-sensitized silver halide, thereby causing reaction of the organic refractive index-modulating agent. Hence, the interference fringes formed by refractive index modulation are recorded.

    摘要： A photographic element comprises a support bearing a cyan dye image-forming unit comprising at least one red-sensitive silver halide emulsion layer having associated therewith at least one cyan dye-forming coupler, a magenta dye image-forming unit comprising at least one green-sensitive silver halide emulsion layer having associated therewith at least one magenta dye-forming coupler, a yellow dye image-forming unit comprising at least one blue-sensitive silver halide emulsion layer having associated therewith at least one yellow dye-forming coupler, wherein at least one of said emulsion layers comprises a) an emulsion with 3D, core/shell grains of at least 0.40 mu m average diameter having a high iodide content in the core of the grain with a shell containing a lesser amount of iodide, b) a one-equivalent image-dye forming coupler, and c) a fragmentable electron donating compound of the formula: X-Y' or a compound which contains a moiety of the formula -X-Y'; wherein X is an electron donor moiety, Y' is a leaving proton H or a leaving group Y, with the proviso that if Y' is a proton, a base, beta , is covalently linked directly or indirectly to X, and wherein: 1) X-Y' has an oxidation potential between 0 and about 1.4 V; and 2) the oxidized form of X-Y' undergoes a bond cleavage reaction to give the radical X and the leaving fragment Y; and, optionally, 3) the radical X has an oxidation potential ≤-0.7V (that is, equal to or more negative than about -0.7V).

    摘要： The present invention relates to a light-sensitive silver halide color multilayer photographic material which comprises a support base having coated thereon at least three red-sensitive emulsion layers having different sensitivity, at least three green-sensitive emulsion layers having different sensitivity, and at least two yellow-sensitive emulsion layers having different sensitivity, wherein (a) a core-shell silver halide emulsion having an average silver iodide content lower than 10% mol is present in at least one of the lowest sensitive red-, green-and yellow layers, (b) a yellow dye forming malonodiamide DIR coupler having in the coupling position thereof a 4,7-dihalogen-2-benzotriazolyl group is present in both the medium sensitive red- and green-sensitive layers, and (c) a yellow dye forming DIR coupler having a 1,2,4-triazolyl group attached to the coupling position, such 1,2,4-triazolyl group comprising a hydrolizable alkoxy-or aryloxy-carbonyl group attached to a benzytlthio substituent on the 1,2,4-triazolyl group is present in at least one of the highest sensitive red- and green-sensitive layers.
