ABSTRACT:
A photographic silver halide photosensitive material includes an infrared sensitive layer which is spectrally sensitized with a combination of at least two J-band type sensitizing dyes so as to have maximum spectral sensitivity at 700 nm or longer wavelength. The photosensitive material has high sensitivity to exposure to a semiconductor laser of 700 nm or longer wavelength. Color separation is improved in the case of color photosensitive material.
