Abstract: A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record and can be used to provide color photographic prints. The element also has a non-light sensitive layer over the red light sensitive color record. This non-light sensitive layer has (1) a hydrophilic colloid in an amount of at least 200 mg/m2 to and including 2,000 mg/m2, (2) matte particles, and (3) an acrylate latex polymer having latex particles having an average size of less than 1 ?m and a glass transition temperature of at least 70° C. The dry weight ratio of the acrylate latex polymer to the hydrophilic colloid is at least 0.8:1 and the dry weight ratio of the acrylate latex polymer to the total matte particles is at least 15:1.

Abstract: A color photographic element has a reflective support and a blue light sensitive color record, a green light sensitive color record, and a red light sensitive color record can be used to provide color photographic prints. The element also has a non-light sensitive interlayer between the green light and red light sensitive color records. This interlayer comprises a hydrophilic colloid and an acrylic latex polymer having a glass transition temperature (Tg) of less than 0° C. The presence of this acrylic latex polymer in the interlayer reduces the formation of a cyan line defect when the color photographic print is folded or creased, such as in photobooks.

Abstract: The invention relates to a photographic element comprising a support and at least three color records comprising at least three light sensitive layers and at least two interlayers, wherein the light sensitive layers include cyan, magenta, or yellow dye-forming coupler, the light sensitive layers include silver halide grains comprising greater than 90% silver chloride, scavengers are included in the interlayers, the ratio of the total level of scavenger to the total level of coupler is from 0.15 to 0.50, the ratio of the total level of scavenger to the total level of silver is from 0.05 to 0.15, and the reciprocity characteristics of the silver halide grains are such that for a separation exposure of 1 microsecond and 0.4 seconds, upon development, the difference in maximum density is 10% or less and a method for processing the element comprising color developing the element for less than 30 seconds.

Abstract: A method for forming a radiation-sensitive high chloride silver halide emulsion is described comprising growing cubical silver halide grains having a central portion accounting for up to 98 percent of total silver of the grains which central portion contains an iridium coordination complex dopant, and chemically sensitizing the surface of the emulsion grains at a pH of at least 5.75. Localized addition of the known in the art reciprocity-controlling iridium dopants to an internal portion of the emulsion grains and chemical finishing of such an emulsion at elevated pH conditions improves reciprocity and latent image stability of the formed high chloride emulsions.

Abstract: A mixer for preparing silver halide grains for photographic use has upper and lower impellers housed in a draft tube. The bottom impeller has flat blades for micromixing silver and halide reactants introduced into the bottom of the draft tube. The upper impeller has pitched blades for macromixing the bulk fluid. The impellers are spaced apart at least the distance of their diameters so that the upper and lower impellers operate independently of one another so that micromixing is independent of macromixing. A flow disrupter structurally associated with the draft tube and positioned above the top impeller prevents vortexing of the fluid during mixing. Baffles may be provided in the draft tube to discourage vortexing.

Abstract: A process for the preparation of a radiation-sensitive silver halide emulsion comprised of high chloride cubical silver halide grains containing from 0.05 to 3 mole percent iodide, based on total silver, where the iodide is incorporated in the grains in a controlled, non-uniform distribution forming a core containing at least 50 percent of total silver, an iodide free surface shell having a thickness of greater than 50 Å, and a sub-surface shell that contains a maximum iodide concentration is disclosed, the process comprising: (a) providing in a stirred reaction vessel a dispersing medium and host high chloride silver halide cubical grains comprising a speed enhancing amount of iodide, and (b) precipitating silver halide onto the host grains by introducing at least a silver salt solution into the dispersing medium at a rate such that the normalized molar addition rate, Rn, is above 3.

Abstract: The invention provides a process for incorporating iridium into silver chloride or silver chlorobromide emulsions containing 90% or more chloride which comprises addition of an iridium salt along with or followed by the addition of bromide to the emulsion, after completion of the precipitation stage of emulsion manufacture. The invention also encompasses the formed emulsions and photographic elements comprising the emulsions.

Abstract: Color photographic materials and methods employ a substrate bearing a silver chloride emulsion. The silver chloride emulsion includes a diamino disulfide and a sulfinate. The diamino disulfide and the sulfinate are included in a weight ratio of from about 1:1 to about 1:20, and provide improved storage stability and reduced high temperature sensitivity during exposure.
