ABSTRACT:
A heat-developable color light-sensitive material comprising a support having thereon at least three silver halide emulsion layers each sensitive to a different spectral wavelength region, one silver halide emulsion layer or a light-insensitive layer adjacent thereto containing a yellow dye-providing compound, a second silver halide emulsion layer or a light-insensitive layer adjacent thereto containing a magenta dye-providing compound and a third silver halide emulsion layer or a light-insensitive layer adjacent thereto containing a cyan dye-providing compound; at least one of said silver halide emulsion layers having a maximum spectral sensitivity at a wavelength of at least 700 nm and a spectral sensitivity at a wavelength 20 nm longer than said maximum spectral sensitivity wavelength of at most 1/10 of said maximum spectral sensitivity.
A heat-developable color light-sensitive material with such spectral sensitivity characteristics in at least one silver halide emulsion layer provides superior color separation from other layers having a sensitivity in the infrared region.
