Silver halide photographic emulsion and silver halide photographic material
摘要:
A silver halide photographic emulsion which contains silver halide grains having a spectral absorption maximum wavelength of less than 500 nm and a light absorption strength of 60 or more, or a spectral absorption maximum wavelength of 500 nm or more and a light absorption strength of 100 or more, wherein at least one of the sensitizing dyes which are used for spectrally sensitizing the emulsion does not have an electric charge in the molecule at all, or forms an inner salt and the molecule does not have an electric charge as a whole and has at least one aromatic ring in the molecule.
