Abstract
A color-developing agent of the formula (1-1): 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): 2 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.
Claims15
A silver halide photographic light-sensitive material, which contains at least one color-developing agent represented by the formula (1-1) on a support:
- 97
- wherein X represents a hydrogen atom or a substituent, and Z represents a carbamoyl, acyl, alkoxycarbonyl, or aryloxycarbonyl group.
An azo dye represented by the following formula (2-1):
- 98
- 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 the formula (2-1).
A silver halide photographic light-sensitive material, which contains an azo dye represented by the following formula (2-1):
- 102
- 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 the formula (2-1).
A silver halide color photographic light-sensitive material, which contains at least one dye-forming compound represented by the following formula (2-5) on a support:
- (Dye)q—X1—Y formula (2-5)
- wherein Dye represents an azo dye represented by the following formula (2-1) or a precursor thereof, X1 represents a single bond or a connecting group which is cleaved in correspondence to or in inverse correspondence to development, Y represents a group which has a nature of generating a difference in diffusibility of the dye component in correspondence to or in inverse correspondence to reaction of a light-sensitive silver salt having a latent image imagewise, Dye is bonded to X1 at a position or positions of at least one of R1 and A in the formula (2-1), q is 1 or 2, and when q is 2, Dye's may be the same or different:
- 106
- 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 the formula (2-1).
