摘要： 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 3.0×10−2 min−1, Rn satisfying the formula: Rn=[Qf×Cf]/M where Qf is the volumetric rate of addition, in L/min, of silver salt solution into the reaction vessel; Cf is the concentration, in moles/L, of the silver salt solution; and M is total moles of silver halide in the host grains in the reaction vessel at the precise moment of addition of the silver salt solution. In a further aspect, this invention is directed towards a photographic recording element comprising a support and at least one light sensitive silver halide emulsion layer comprising silver halide grains prepared as described above. The advantages of the invention are generally accomplished in accordance with the discovery that when the exterior portion of profiled silver iodochloride grains are grown under specific conditions of high molar addition rates, iodochloride emulsions of enhanced sensitivity and photographic curve shape are produced, as speed can be increased while keeping fog to a low level.
