Method of manufacturing a silver halide emulsion |
摘要 |
A method for manufacturing a silver halide emulsion comprising core/shell type silver iodobromide grains, said emulsion having an average iodide content of 3 mol % or more, each of the grains having two or more phases different in silver iodide content from each other which comprises an inner phase having silver iodide content of 10 mol % or more and an outermost phase having a silver iodide content lower than the iodide content of the inner phase, wherein a compound represented by the following formula [I] is present at least in a process prior to a desalting process: formula [I] <IMAGE> wherein Z represents a group of atoms necessary to form a five- or six-membered heterocycle, which may be a condensed ring; and M represents an alkali metal atom or ammonium group.
