Abstract
A silver halide photographic light-sensitive material having high sensitivity and having a desired spectral sensitivity distribution. A silver halide photographic light-sensitive material comprising at least one multichromophore dye compound having at least two dye chromophores connected by covalent bonding or coordinate bonding, at least two of the dye chromophores forming a dye chromophore group and the light absorption of the dye chromophore group differing from the sum of individual light absorptions of respective dye chromophores constituting said dye chromophore group.

A silver halide photographic light-sensitive material comprising at least one multichromophore dye compound having at least two dye chromophores connected by covalent bonding or coordinate bonding, at least two of said dye chromophores forming a dye chromophore group, the light absorption of said dye chromophore group differing from the sum of individual light absorptions of respective dye chromophores constituting said dye chromophore group, and the absorption maximum wavelength of said dye chromophore group is longer, by 20 nm or more, than the maximum wavelength of the sum of the absorptions of individual dye chromophores.
