Abstract:
A silver halide emulsion which has high sensitivity and a high gamma value regardless of exposure mode, is excellent in coating fluid stability in stagnation and latent-image stability, and enables high-quality prints to be always obtained stably, and which is excellent especially in latent-image stability in digital exposure where the photographic sensitive material is exposed at a high luminance for a short time. The silver halide emulsion contains silver halide particles having a silver chloride content of 90 mol% or higher, a silver iodide content of 0 to 2.0 mol%, and a silver bromide content of 0.02 to 5.0 mol% and containing therein two or more Group 8 metal compounds including one or more iridium compounds. This emulsion is characterized in that the silver halide particles have been sensitized with selenium in the presence of a compound represented by the following general formula (S).
