<p>Preparation method of a silver halide emulsion is disclosed, in which the silver halide emulsion contains tabular grains having a mean equivalent circle diameter of 0.1 to 10.0 mu m, a mean grain thickness of 0.01 to 0.3 mu m and an aspect ratio of 1.5 to 300, the emulsion is prepared by a process comprising: (a) forming the tabular silver halide grains in the presence of fine silver halide grains containing at least a metal selected from the group of indium, gallium and metals in Groups 8, 9 and 10 of the periodical table and (b) subjecting the tabular silver halide grain emulsion to ultrafiltration to remove a salt-containing solution from a reaction mixture solution in the growth process of the tabular grains.</p> |
