摘要： An improved silver halide photographic material having at least one layer of a light-sensitive silver halide emulsion that is spectrally sensitized with a sensitizing dye of the following general formula (1) to light having a wavelength of 750 nm and above. Said silver halide emulsion is prepared by a process which comprises generating silver halide grains by adding a solution of a water-soluble silver salt and a solution of a water-soluble halide to a solution containing a protective colloid, aggregating the generated silver halide grains with a polymeric flocculating together with the protective colloid, and removing the dissolved matter; ##STR1## where Z.sub.1 and Z.sub.3 each represents the non-metallic atomic group necessary to form an optionally substituted benzothiazole, benzoxazole, naphthothiazole or naphthoxazole nucleus; R.sub.1 and R.sub.2 each represents a saturated or unsaturated aliphatic group; Z.sub.2 represents a 5- or 6-membered ring of carbon atoms; A represents a hydrogen atom when Z.sub.2 is a 6-membered ring; X.sup..crclbar. is an anion; and n is 1 or 2.
