ABSTRACT:
The present invention provides an emulsion of high silver chloride content tabular silver halide grains with {100} planes as main planes having an excellent color sensitizability, gradation and preservability which can be quickly processed and a photographic light-sensitive material comprising such an emulsion. A novel silver halide emulsion is provided, comprising tabular silver halide grains having {100} planes as two main parallel planes, an aspect ratio of from not less than 2 to not more than 15, a silver chloride content of not less than 60 mol % and a silver salt present on the surface thereof more difficultly-soluble than silver chloride, in a proportion of not less than 50% of all the silver halide grains contained therein as calculated in terms of projected area.
