摘要： A photographic emulsion is disclosed comprised of a dispersing medium and radiation-sensitive silver halide grains with greater than 50 percent of total grain projected area being accounted for by grains containing a host portion of a face centered cubic rock salt crystal lattice structure and a first epitaxial phase containing greater than 90 mole percent iodide. The host portion is tabular, being bounded by an exterior having first and second parallel major faces joined by a peripheral edge. The first epitaxial phase accounts for less than 60 percent of total silver, and the first epitaxial phase is restricted to a portion of the exterior of the host portion that includes at least 15 percent of the major faces.

摘要： A process is disclosed of preparing silver halide emulsions containing tabular grains bounded by [100] major faces comprised of the steps of (1) introducing silver and halide salts into a dispersing medium and (2) maintaining conditions within the dispersing medium that promote the formation of tabular grains bounded by [100] major faces. The process is characterized in that of the tabular grains bounded by [100] major faces a portion accounting for 50 percent of total grain projected area selected on the criteria of adjacent major face edge ratios of less than 10 and thicknesses of less than 0.3 mu m internally at their nucleation site contain iodide and at least 50 mole percent chloride, at least the selected portion of the tabular grains being formed ty nucleation in a continuous double jet reaction in the presence of iodide with chloride accounting for at least 50 mole percent of the halide present in the dispersing medium and the pC1 of the dispersing medium being maintained in the range of from 0.5 to 3.5. Following nucleation tabular grain growth is undertaken in a reaction vessel which receives emulsion from the continuous double jet reactor until the tabular grains having a thickness of less than 0.3 mu m exhibit achieve a selected average aspect ratio.

Greater than 30 percent of the grain population is accounted for by tabular grains having a thickness of less than 0.3 νm and having {100} major faces. In one preferred form of the invention tabular grains are formed by nucleation in the presence of iodide with chloride accounting for at least 50 mole percent of the halide present in the dispersing medium and the pCl of the dispersing medium being maintained in the range of from 0.5 to 3.5.
