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.
Claims14
An azo dye represented by the following formula (2-1):
- wherein R1 represents a hydrogen atom or a substituent, and A is a group to give a coupler which has been used in a silver halide photographic light sensitive material.
An azo dye represented by the following formula (2-1):
- wherein R1 represents a hydrogen atom or a substituent, and A in the formula (2-1) is a group represented by the following formula (2-2):
- wherein R2, R3, R4 and R5 each represents a hydrogen atom or a substituent, and R2 and R3 and/or R4 and R5 may bond together to form a ring, and * represents a position which is bonded to the azo moiety in the formula (2-1).
An azo dye represented by the following formula (2-1):
- wherein R1 represents a hydrogen atom or a substituent, and A in the formula (2-1) is a group represented by the following formula (2-3):
- wherein Cα represents a carbon atom, EWG represents a cyano, carbamoyl or alkoxycarbonyl group, M represents a group of atoms necessary to form together with the Cα a 5- or 6-membered aromatic heteroring, and * represents a position which is bonded to the azo moiety in the formula (2-1).
An azo dye represented by the following formula (2-1):
- wherein R1 represents a hydrogen atom or a substituent, and A in the formula (2-1) is a group represented by the following formula (2-4):
- wherein R6 represents a hydrogen atom or a substituent, Cβ represents a group of atoms necessary to form together with the N—C—NH a 5- or 6-membered aromatic heteroring, and * represents a position which is bonded to the azo moiety in the formula (2-1).
