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.
