ABSTRACT:
A silver halide emulsion is described, which contains tabular silver halide grains having {100} faces as the parallel two major planes, having an aspect ratio of 2 or more and having a mean silver chloride content of 50 mol % or more, in an amount of 50% or more of the total projected area of all the silver halide grains therein, and which is spectrally sensitized with a particular trimethine dye of formula (I). A photographic material having the emulsion has a high sensitivity and good storability and can be processed rapidly.
