SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

PURPOSE:To obtain the silver halide photosensitive material superior in color sensitivity and graininess and sharpness and capable of changing a tone by use of a tone changing filter by designing so as to select an exposure wavelength in each wavelength region and to enable to obtain different tones. CONSTITUTION:The photosensitive material is a black-and-white photosensitive material having a silver halide emulsion comprising >=2 constituents different in spectral sensitivity in each photosensitive wavelength region of 400-500nm, 500-600nm, and >=600nm, and it is designed so as to enable to obtain different tones by selecting the exposure wavelength in each photosensitive wavelength region. This black-and-white photosensitive material has one silver halide emulsion layer on a support. A panchromatic black-and-white photographic printing paper is obtained by applying this emulsion having >=2 characteristic constituents different in spectral sensitivity to each flue green read sensitive wave length to form one emulsion layer.
