ABSTRACT:
A silver halide color photosensitive material comprises a blue-sensitive layer, a green-sensitive layer, a red-sensitive layer and a non-light-sensitive layer on a support. The silver halide color photosensitive material contains a compound selected from the following type 1 and type 2 compounds, and wherein the blue-sensitive layer meets the relationship of the following formula (I):in-line-formulae description="In-line Formulae" end="lead"?SB(370 nm)/SB(420 nm)<0.7  (I)in-line-formulae description="In-line Formulae" end="tail"?wherein SB(λ) represents a spectral sensitivity at a wavelength of λ,(type 1)a compound capable of undergoing a one-electron oxidation to thereby form a one-electron oxidation product thereof, wherein the one-electron oxidation product is capable of releasing further one or more electrons accompanying a subsequent bond cleavage reaction, and(type 2)a compound capable of undergoing a one-electron oxidation to thereby form a one-electron oxidation product thereof, wherein the one-electron oxidation product is capable of releasing further one or more electrons accompanying a subsequent bond-forming reaction.
