| abstract |
A silver halide emulsion containing negative working silver halide grains each comprising a core of silver bromide or silver bromoiodide, a first coating layer exterior the core of silver iodide or silver bromoiodide, and a second coating layer exterior the first coating layer composed of silver bromide or silver bromoiodide different from that of the first coating layer in halide composition, and having a projected area diameter-to-thickness ratio of less than 5, in which: (1) the first coating layer contains more iodide than the core by 10 mol % or more; and (2) silver in the first coating layer accounts for 0.01 to 30 mol % of the total silver in the grain. |
