Silver halide color photographic material and process for the formation
of color images thereon
Abstract:
A novel silver halide color photographic material is provided which comprises a support having coated thereon at least three silver halide emulsion layers having maximum spectral sensitivities in at least three sensitive wavelength ranges of 400 nm to 500 nm, 500 nm to 570 nm and 650 nm to 730 nm and is sensitive to said three sensitive wavelength ranges to form yellow, magenta and cyan dye images, respectively, characterized in that said silver halide color photographic material has additionally at least one function to provide a maximum spectral sensitvity in wavelength range other than said three sensitive wavelength ranges and to form any of yellow, magenta or cyan dye image by an exposure to the light of said other range. A color image formation method is also disclosed which comprises exposing said silver halide color photographic material to light in a print exposure process in combination with a scanning exposure process, and then developing said silver halide color photographic material.
