Abstract (en)
[origin: EP0412379A1] A silver halide photographic light-sensitive material is disclosed which comprises at least one dye which is insoluble in water and is represented by formula (1) below and a silver halide photographic light-sensitive material is also disclosed which comprises at least one dye which is insoluble in water and is represented by formula (1) and at least one dye which is insoluble in water and is represented by formula (2) below: <CHEM> wherein R<1> represents an alkyl group, a cycloalkyl group, an aryl group, a heterocyclic group, a carboxyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group or a cyano group; R<2> represents a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a hydroxy group, an amino group, a carbamoyl group; a sulfamoyl group or an alkoxycarbonyl group; R<2> may form a five or six membered ring with the benzene ring; n represents 0 or 1, and m represents 1 to 5; with the proviso that at least one alkyl chain which has four or more carbon atoms is contained within R<1> and R<2>; and where m is 2 or more the R<2> groups may be the same or different, <CHEM> wherein X and Y may be the same or different, each representing a cyano group, a carboxyl group, an alkylcarbonyl group, an arylcarbonyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, a sulfonyl group or a sulfamoyl group, with the proviso that where the combination of X and Y is (cyano group, arylcarbonyl group), (cyan group, alkylcarbonyl group) or (cyano group, sulfonyl group) are excluded; R<3> and R<4> may be the same or different, each representing a hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a hydroxy group, a carboxyl group, an amino group, a carbamoyl group, a sulfamoyl group or an alkoxycarbonyl group; R<5> and R<6> may be the same or different, each representing a hydrogen atom, an alkyl group or an aryl group, and R<5> and R<6> may form a five or six membered ring; and R<3> and R<5>, or R<4> and R<6>, may be joined together to form a five or six membered ring.
