Silver halide color photosensitive material
View Patent ↗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): S B (370 nm)/S B (420 nm)<0.7 (I) wherein S B (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.
1. A silver halide color photosensitive material comprising at least one each of a blue-sensitive layer, a green-sensitive layer, a red-sensitive layer and a non-light-sensitive layer on a support, wherein the silver halide color photosensitive material contains a compound selected from among the following type 1 and type 2 compounds, and wherein the blue-sensitive layer meets the relationship of the following formula (I):
S B (370 nm)/S B (420 nm)<0.7 (I)
wherein S B (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.
2. The silver halide color photosensitive material according to claim 1 , wherein the silver halide color photosensitive material further contains at least one fluorinated surfactant selected from the group consisting of compounds represented by formula (A) and compounds represented by formula (B):
wherein each of R B3 , R B4 and R B5 independently represents a hydrogen atom or substituent, each of A and B independently represents a fluorine atom or hydrogen atom, each of n B3 and n B4 is independently an integer of 4 to 8, each of L B1 and L B2 independently represents a substituted or unsubstituted alkylene group, substituted or unsubstituted alkyleneoxy group, or bivalent linking group composed of a combination thereof, m B is 0 or 1, and M represents a cation;
wherein R C1 represents a substituted or unsubstituted alkyl group, provided that the substituent does not include a fluorine atom, R CF represents a perfluoroalkylene group, A represents a hydrogen atom or fluorine atom, L C1 represents a substituted or unsubstituted alkylene group, substituted or unsubstituted alkyleneoxy group, or bivalent linking group composed of a combination thereof, one of Y C1 and Y C2 represents a hydrogen atom while the other represents -L C2 -SO 3 M wherein L C2 represents a single bond or substituted or unsubstituted alkylene group, and M represents a cation.
