Ink composition

An ink composition comprising:

• a dye (C-1) represented by Formula (C-1) below;
• a dye (C-2) including at least one of C.I. Direct Blues 86 and 199;
• an alkylene oxide adduct of an acetylene glycol having a main chain of 12 or more carbon atoms;
• an acetylene glycol having a main chain of 10 or more carbon atoms;
• and
• a polyoxyalkylene alkyl ether,
• wherein the content ratio A of the dye (C-1) and the dye (C-2) (the dye (C-1):the dye (C-2)) is 7:3 to 9.5:0.5, and
• the content of the dye (C-1) is 2.0 mass % to 5.0 mass %,
• in Formula (C-1),
• R2, R3, R6, R7, R10, R11, R14, and R15 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 hydroxyl 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, and these groups may further have a substituent;
• 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, and at least one of Z1, Z2, Z3, and Z4 has an ionic hydrophilic group as a substituent;
• l, m, n, p, q1, q2, q3, and q4 each independently represent 1 or 2;
• and
• M1 represents a hydrogen atom, a metal element, a metal oxide, a metal hydroxide, or a metal halide.
