摘要： A radiation sensitive emulsion is disclosed containing iridium doped composite silver halide grains comprised of (a) host portions having an average aspect ratio of less than 1.3 and consisting essentially of monodisperse silver iodochloride grains containing from 0.05 to 3 mole percent iodide, based on total silver forming the host portions, with maximum iodide concentrations located nearer the surface of the host portions than their center and (b) epitaxially deposited portions containing the iridium dopant and silver bromide accounting for from 0.1 to 5 mole percent of total silver forming the composite grains. The emulsions are prepared by (a) first providing an emulsion containing grains which form the host portions of the grains and (b) modifying the performance properties of the host grains by a combination of silver bromide addition, iridium dopant incorporation and antifoggant addition, in which, prior to antifoggant addition, silver bromide in the amount of from 0.1 to 5.0 mole percent, based on total silver, is added to the host grain emulsion and deposited onto the host grains in the presence of the iridium dopant to be incorporated. The emulsions of the invention demonstrate generally acceptable photographic characteristics, increased speed, and increases in contrast as exposure intensities are increased.
