Silver halide color photosensitive material
A silver halide color photosensitive material containing at least one compound selected from the below defined compound (A-1) and/or (A-2) which does not substantially react with a developing agent oxidation product, and which is capable of substantially enhancing the sensitivity of the photosensitive material by addition thereof as compared with that exhibited when the compound is not added, and at least one compound represented by the below defined general formula (B), compound (A-1): a heterocyclic compound having 1 or 2 hetero atoms; and compound (A-2): a compound selected from an oxadiazole derivative, a thiadiazole derivative and 1,2,4-triazole derivative having an amino group, and general formula (B): Rf-X-M wherein Rf represents an alkyl group having 1 to 6 carbons which is substituted with at least one fluorine atom; X represents a divalent coupling group or a single bond; and M represents an anionic group, a cationic group or a betaine group.
1 . A silver halide color photosensitive material comprising a support and, superimposed thereon, at least one red-sensitive layer, at least one green-sensitive layer, at least one blue-sensitive layer and at least one protective layer, containing at least one compound selected from the below defined compound (A-1) and/or (A-2) which does not substantially react with a developing agent oxidation product, and which is capable of substantially enhancing the sensitivity of the silver halide photosensitive material by addition thereof as compared with that exhibited when the compound is not added, and at least one compound represented by the below defined general formula (B),
compound (A-1): a heterocyclic compound having 1 or 2 hetero atoms; and
