    摘要： High aspect ratio tabular grain silver halide emulsions, photographic elements incorporating these emulsions, and processes for the use of the photographic elements are disclosed. In the tabular grain emulsions the silver halide grains having a thickness of less than 0.5 micron (preferably less than 0.3 micron) and a diameter of at least 0.6 micron have a high aspect ratio and account for at least 50 percent of the total projected area of the silver halide grains present. Silver salt is epitaxially located on and substantially confined to selected surface sites of the tabular silver halide grains.

    摘要： Radiation-sensitive photographic emulsions are disclosed comprised of a dispersing medium and silver halide grains the halide content of which is at least 50 mole percent chloride, based on silver. The silver halide grains include tabular grains having a thickness of less than 0.5 micron, a diameter of at least 0.6 micron, and an average aspect ratio greater than 8:1 which account for at least 50 percent of the total projected area of the silver halide grains. The tabular grains have two opposed substantially parallel major crystal faces lying in {111} crystal planes and exhibiting at least one of the following features: (1) at least one peripheral edge lying parallel to a crystallographic vector lying in the plane of one of the major faces and (2) bromide and/or iodide incorporated in a central grain region. The tabular grains are formed in the presence of an aminoazaindene and a peptizer having a thioether linkage.

    摘要： Processes are disclosed for producing dye images employing photographic elements which comprise a support and coated thereon, at least one radiation-sensitive colorforming layer unit. This layer unit includes a substantially uniform distribution of catalyst and a radiationsensitive, high iodide silver halide emulsion. A first method for producing dye images after imagewise exposure of the photographic element comprises the steps of imagewise poisoning the catalyst with iodide ion by developing the silver iodide containing silver halide emulsion and thereafter employing the remaining unpoisoned catalyst to permit a redox reaction between a peroxide oxidizing agent and a dye-image-generating reducing agent. In a preferred element the high iodide silver halide emulsion is comprised of multifaceted, radiation-receptive silver iodide crystals and silver chloride crystals forming epitaxial junctions with the silver iodide crystals. A dye image of opposite sense can be produced using the preferred element by the steps of poisoning the catalyst; selectively developing the silver chloride portion of the silver halide emulsion; and amplifying the resulting silver image using the peroxy redox amplification reaction.
