A dye ink composition comprising:
- a compound A represented by the following general formula (I-1);
- a compound B represented by the following general formula (I-2);
- at least one of a compound C-I represented by the following general formula (I-3-1) or a compound C-II represented by the following general formula (I-3-2);
- a compound D represented by the following general formula (I-4);
- and
- water,
- wherein, in the general formulae (I-1), (I-2), (I-3-1), (I-3-2), and (I-4), each Z1 represents an alkyl group, an aryl group, or a heterocyclic group, the alkyl group, the aryl group, and the heterocyclic group having a substituent that has at least one ionic hydrophilic group;
- a plurality of Z1's in the general formulae (I-1), (I-2), (I-3-1), and (I-3-2) may be the same as or different from each other;
- wherein, in the general formulae (I-2), (I-3-1), (I-3-2), and (I-4), each Z2 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic group;
- each Z2 does not have an ionic hydrophilic group;
- and a plurality of Z2's in the general formulae (I-3-1), (I-3-2), and (I-4) may be the same as or different from each other;
- and
- wherein, in the dye ink composition, in a case where a mass of the compound A is represented by W1, a mass of the compound B is represented by W2, a sum of a mass of the compound C-I and a mass of the compound C-II is represented by W3, a mass of the compound D is represented by W4, and a total sum of W1, W2, W3, and W4 is represented by WA1,
- a ratio of W1 to WA1 is 6.0% to 35.0% by mass,
- a ratio of W2 to WA1 is 20.0% to 45.0% by mass,
