Silver halide photographic material comprising hole-injection-type sensitizing dye(s) and supersensitizing compound(s)

A silver halide photographic material comprising a support having provided thereon at least one silver halide emulsion layer comprising a substantially surface-latent-image silver halide emulsion which comprises at least one hole-injection sensitizing dye in an amount of 4.times.10.sup.-4 mol or more per mol of silver in the emulsion and further comprises at least one supersensitizing compound, wherein one of the at least one hole-injection sensitizing dye and one of the at least one supersensitizing compound satisfy the following requirements:

• (1) when both said one of the at least one hole-injection sensitizing dye and said one of the at least one supersensitizing compound have been adsorbed onto the silver halide grains constituting the emulsion, the emulsion has a maximum absorption wavelength of longer than 545 nm;
• (2) when said one of the at least one hole-injection sensitizing dye is singly adsorbed onto a standard, negative silver iodobromide emulsion which is employed for the intended evaluation and which gives a surface negative image by exposure, the relative quantum yield of the negative sensitivity of the emulsion is smaller than 0.6;
• (3) when both said one of the at least one hole-injection sensitizing dye and said one of the at least one supersensitizing compound are adsorbed onto a standard, internally fogged reversal silver iodobromide emulsion which is employed for the intended evaluation and which gives an internal reversal image by exposure, the degree of intrinsic desensitization of the reversal sensitivity of the emulsion is smaller than 0.2 as log E;
• and
• (4) when both said one of the at least one hole-injection sensitizing dye and said one of the at least one supersensitizing compound are adsorbed onto the standard, internally fogged reversal silver iodobromide emulsion referred to in (3), the relative quantum yield of the reversal sensitivity of the emulsion is 0.8 or more.
