摘要： A chemically and spectrally sensitized ultrathin tabular grain emulsion is disclosed including tabular grains (a) having {111} major faces, (b) containing greater than 70 mole percent bromide, based on silver, (c) accounting for greater than 90 percent of total grain projected area, (d) exhibiting an average equivalent circular diameter of at least 0.7 .mu.m, and (e) exhibiting an average thickness of less than 0.07 .mu.m.It has been observed that increased speed and contrast as well as improvements in speed-granularity relationships can be realized when the surface chemical sensitization sites include epitaxially deposited silver halide protrusions forming epitaxial junctions with the tabular grains, the protrusions (a) being located on up to 50 percent of the surface area of the tabular grains, (b) having a higher overall solubility than at least that portion of the tabular grains forming epitaxial junctions with the protrusions, and (c) forming a face centered cubic crystal lattice.In further improving photographic performance by incorporating a photographically useful dopant, it has been observed that thinner tabular grains can be realized by locating the dopant in the protrusions. Still further improvements in photographic sensitivity can be realized by selecting the dopant to act as a shallow trap for photoelectrons.

摘要： A process is disclosed of preparing radiation-sensitive tabular grain silver bromoiodide emulsions. This is achieved by providing in a reaction vessel an emulsion comprising a dispersing medium and high iodide silver halide grains. The mean diameter of the silver halide grains is less than 0.1 micron, and the concentration of iodide is less than 10.sup.-2 mole per liter of the emulsion. Upon concurrently running into the reaction vessel silver and bromide, a high aspect ratio tabular grain silver bromoiodide emulsion is obtained.
