Abstract
A color-developing agent of the formula (1-1): wherein X represents a hydrogen atom or a substituent, and Z represents a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group. An azo dye of the formula (2-1): wherein R1 represents a hydrogen atom or a substituent, and A represents a group of atoms necessary to form the azo dye by the compound of formula (2-1). A silver halide photographic light-sensitive material containing any of the color-developing agent and the azo dye in at least one photographic constitutional layer.
Claims7

- wherein X represents a hydrogen atom or a substituent with the proviso that X is not a phenyl group, and Z represents a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group.
A color-developing agent, represented by the following formula (1-1):
- wherein X represents a hydrogen atom or a substituent selected from the group consisting of halogen atoms, noncyclic alkyl, cycloalkyl, bicycloalkyl, alkyl having a tricyclo structure or higher structure, noncyclic alkenyl, cycloalkenyl, bicycloalkenyl, alkynyl, naphthyl, substituted aryl, heterocyclic , cyano, hydroxyl, nitro, carboxyl, alkoxy, aryloxy, silyloxy, heterocyclic oxy, acyloxy, carbamoyloxy, alkoxycarbonyloxy, aryloxycarbonyloxy, amino, acylamino, aminocarbonylamino, alkoxycarbonylamino, aryloxycarbonylamino, sulfamoylamino, alkyl- and aryl-sulfonylamino, mercapto, alkylthio, arylthio, heterocyclic thio, sulfamoyl, sulfo, alkyl- and aryl-sulfinyl, alkyl- and aryl-sulfonyl, acyl, aryloxycarbonyl, alkoxycarbonyl, carbamoyl, arylazo and heterocyclic azo, imido, phosphino, phosphinyl, phosphinyloxy, phosphinylamino and silyl, and
- Z represents a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group.
A color-developing agent, represented by the following formula (1-1):
- wherein x in the formula (1-1) is a hydrogen atom or a substituent further comprising at least one substituent selected from the group consisting of —COOH, —NHSO2R, —SO2NHR, —SO2NHCOR, —CONHSO2R, —NHCONHSO2R, —SO2NHCONRR, —OH and —SH, in which R represents an alkyl, aryl or aromatic heterocyclic group which may be substituted, and R's may be the same or different from each other and may bond together to form a ring,
- and Z represents a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group.
