Abstract
Disclosed is a silver halide photographic material having at least one silver halide emulsion layer containing a silver halide photographic emulsion, wherein the silver halide photographic emulsion comprises spectrally sensitized tabular silver halide grains having an average aspect ratio of from 8 to 100, and having light absorption strength by a sensitizing dye per unit surface area of the grain surface of 100 or more.

A silver halide photographic material having at least one silver halide emulsion layer containing a silver halide photographic emulsion, wherein said silver halide photographic emulsion comprises spectrally sensitized tabular silver halide grains having an average aspect ratio of from 8 to 100, and having light absorption strength by a sensitizing dye per unit surface area of the grain surface of 100 or more;
- wherein the light absorption strength by a sensitizing dye per unit surface area is defined as the value obtained by integrating optical density Log [I.sub.0 /(I.sub.0 -I)] to wave number (cm.sup.-1), taking the incident light amount on the unit surface area of the grain as I.sub.0 and the light amount absorbed by the sensitizing dye on the surface as I, and the region of integration is from 5,000 cm.sup.-1 to 35,000 cm.sup.-1.
A silver halide photographic material having at least one silver halide emulsion layer containing a silver halide photographic emulsion, wherein said silver halide photographic emulsion comprises tabular silver halide grains spectrally sensitized at spectral absorption maximum wavelength of 500 nm or less having an average aspect ratio of from 8 to 100, and having light absorption strength by a sensitizing dye per unit surface area of the grain surface of 60 or more and less than 100;
- wherein the light absorption strength by a sensitizing dye per unit surface area is defined as the value obtained by integrating optical density Log [I.sub.0 /(I.sub.0 -I)] to wave number (cm.sup.-1), taking the incident light amount on the unit surface area of the grain as I.sub.0 and the light amount absorbed by the sensitizing dye on the surface as I, and the region of integration is from 5,000 cm.sup.-1 to 35,000 cm.sup.-1.
