A silver halide color photographic photosensitive material which has been spectrally sensitized to light of wavelengths greater than of about 670 nm in which are highly sensitive to light of wavelength greater than about 670 nm and sufficiently insensitive to visible light having a shorter wavelength. The photosensitive materials comprises a silver halide photosensitive layer containing the yellow coupler, a silver halide photosensitive layer containing a magenta coupler, a silver halide photosensitive layer containing a cyan coupler and at least one non-photosensitive hydrophilic layer. Each of the photosensitive layers are spectrally sensitized such that they have different peak spectral sensitivities at light wavelengths greater than about 670 nm. The photosensitive material also comprises at least one first dye which has an absorption peak wavelength in the wavelength region longer than 400 nm but at least 20 nm shorter than the shortest of the wavelengths which form the peak values of the spectral sensitivities of the photosensitive layers. This first dye can be included in a photosensitive layer and/or a non-photosensitive hydrophilic colloid layer. The photosensitive material can also contain at least one second dye which has an absorption peak wavelength at a wavelength region of 670 nm to 1000 nm.
A process for preparing color images comprising processing an imagewise exposed photographic material with a color developer which is essentially sulfite ion free, the photographic material comprising at least three silver halide photosensitive layers including a silver halide photosensitive layer comprising a silver halide emulsion containing a yellow coupler, a silver halide photosensitive layer comprising a silver halide emulsion containing a magenta coupler and a silver halide photosensitive layer comprising a silver halide emulsion containing a cyan coupler, and at least one non-photosensitive hydrophilic layer,
