Silver halide photographic light-sensitive material

摘要

A silver halide photographic light-sensitive material containing at least one methine dye which consists of an azulene nucleus, at least one of 10 carbon atoms of which is replaced by chalcogen atom(s) or nitrogen atom(s), and further whose 7-membered ring part is substituted with a methine bond having at the terminal an auxochrome which forms a conjugated resonance chromophore together with 10 pi electron system of the nucleus is provided. Silver halide photographic light-sensitive materials of the invention are spectrally sensitized in long wavelength region, and have improved photographic performances such as sharpness and color resolution.
