摘要： A process for precipitating a high bromide silver halide emulsion in an aqueous medium is disclosed comprising growing nucleated silver halide grains in a reaction vessel in the presence of a peptizer comprising a water dispersable starch to form high bromide radiation-sensitive silver halide grains, wherein the majority of grain growth in the reaction vessel is performed at a pH of less than 3.5. Growth of high bromide silver halide emulsion grains in the presence of a starch peptizer at low pH in accordance with the invention results in emulsion grains with lower fog, even in the absence of the use of strong oxidizing agents during grain precipitation.

摘要： A process for precipitating a high bromide silver halide emulsion in an aqueous medium is described comprising precipitating high bromide radiation-sensitive silver halide grains in a reaction vessel in the presence of a peptizer comprising a water dispersable starch, wherein a strong oxidizing agent is added to the reaction vessel during or after the precipitation at a pH of less than 4.0 such that an oxidation potential of at least 650 mV (Ag/AgCl ref.) is achieved. A reduction in the rate of reaction between strong oxidants such as bromine and starch at such low pH has been found to enable an advantageous decrease in the amount of oxidant required to achieve and maintain a high oxidation potential during emulsion grain precipitation. Starch, unlike gelatin, also advantageously has adequate stability at the combination of high acidity and high emulsion precipitation temperatures.

摘要： A process is disclosed for preparing high chloride {100} tabular grain emulsions containing crystal lattice dislocations in peripheral regions of the tabular grains. In the initial step of the process a radiation-sensitive high chloride {100} tabular grain emulsion is produced to provide host grains. Lateral growth lateral growth of the {100} major surfaces of the tabular grains is extended by precipitating a high chloride peripheral region onto the host tabular grains. After the host grains have been provided an iodide ion source compound with a maximum second order reaction rate constant within the dispersing medium of less than 1.times.10.sup.3 mole.sup.-1 sec.sup.-1 is introduced into the host emulsion to release iodide ions for incorporation into the tabular grains at their peripheral edges by chloride ion displacement. In the resulting emulsion 10 or more crystal lattice dislocations extending inwardly from the peripheral edges of the {100} tabular grains are observed. The dislocations in the peripheral and, particularly, corner regions of the tabular grains increase their sensitivity.
