摘要： Surface sensitive photographic low pAg silver halide emulsions and elements are provided which contain (1) a photographic infrared spectral sensitizing dye having a polarographic cathodic halfwave potential more positive than about -1.20 volts, said dye being employed in the emulsion at a concentration which results in at least about 0.3 log E desensitization of a test portion of the emulsion, when the test portion of the emulsion is coated on a support, sensitometrically exposed and developed and (2) a silver complexing azaindene in an amount effective to reduce the desensitization caused by the spectral sensitizing dye. Photographic emulsions in accordance with this invention exhibit higher speeds in the spectrally sensitized region (i.e., higher minus blue speeds) than prior art surface-sensitive emulsions. In addition, use of the emulsions in accordance with this invention permits the use of higher dye concentrations and results in emulsions having excellent keeping qualities and much lower fog levels.
