Claims20
An ink set comprising:
- a magenta ink composition;
- a cyan ink composition;
- a yellow ink composition;
- and
- a black ink composition,
- wherein the magenta ink composition contains at least one compound represented by the following general formula (1),
- the cyan ink composition contains at least one compound represented by the following general formula (2),
- the yellow ink composition contains at least one compound selected from the following group Y, and
- the black ink composition contains at least one compound selected from the following group BK,
- wherein, in the general formula (1), R1, R5, R6, and R10 each independently represent an alkyl group that may have a substituent, R2, R3, R7, R8, R11, R12, R13, R14, R15, R16, R17, R18, R19, and R20 each independently represent a hydrogen atom or a substituent, and M1 and M2 each independently represent a hydrogen atom, an alkali metal ion, or an ammonium ion,
- wherein, in the general formula (2), R21, R22, R23, R24, R25, R26, R27, and R28 each independently represent a hydrogen atom, a halogen atom, an alkyl group, a cycloalkyl group, an alkenyl group, an aralkyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxy group, a nitro group, an amino group, an alkylamino group, an alkoxy group, an aryloxy group, an amide group, an arylamino group, a ureido group, a sulfamoylamino group, an alkylthio group, an arylthio group, an alkoxycarbonylamino group, a sulfonamide group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, a heterocyclic oxy group, an azo group, an acyloxy group, a carbamoyloxy group, a silyloxy group, an aryloxycarbonyl group, an aryloxycarbonylamino group, an imide group, a heterocyclic thio group, a phosphoryl group, an acyl group, or an ionic hydrophilic group, which may further have a substituent, and Z1, Z2, Z3, and Z4 each independently represent a substituted or unsubstituted alkyl group, a substituted or unsubstituted cycloalkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aralkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group, where at least one of Z1, Z2, Z3, or Z4 has an ionic hydrophilic group as a substituent,
- wherein, in the general formulae (Y1) to (Y9), each M independently represents a hydrogen atom, a lithium ion, a sodium ion, a potassium ion, or an ammonium ion,
- wherein, in the general formulae (BK1) to (BK9), each M independently represents a hydrogen atom, a lithium ion, a sodium ion, a potassium ion, or an ammonium ion.
