ABSTRACT:
There is provided a silver halide photographic material which comprises a support having thereon at least three kinds of silver halide light-sensitive emulsion layers differing from one another in color sensitivity, at least two kinds of which comprise silver halide emulsion grains sensitized spectrally with sensitizing dyes providing their respective spectral sensitivity maxima at wavelength of longer than about 570 nm, with the photographic material further containing at least one water-soluble dye which is selected from eight groups having specified structural formulae respectively and has an absorption maximum at wavelengths longer than about 570 nm, thereby acquiring an aptitude with scanning exposure using at least two kinds of light sources capable of emitting monochromatic high-intensity beams of wavelengths longer than 570 nm and ensuring high resolving power without attended by aggravation of color separation.
