An aqueous ink jet composition of the present disclosure includes: at least one dye selected from the group consisting of C.I. Solvent Yellow 160:1, C.I. Disperse Yellow 82, and C.I. Disperse Yellow 184; a material A which is at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), an ethylene oxide adduct of tristyrylphenol, a derivative of an ethylene oxide adduct of tristyrylphenol, a polyalkylene glycol, and a derivative of a polyalkylene glycol; and an anionic dispersant.

Aqueous ink jet composition

An aqueous ink jet composition contains: C.I. Disperse Red 364; a material A which is at least one compound selected from the group consisting of a compound represented by the following formula (1), a compound represented by the following formula (2), an ethylene oxide adduct of tristyrylphenol, a derivative of the ethylene oxide adduct of tristyrylphenol, a polyalkylene glycol, and a derivative of the polyalkylene glycol; and an anionic dispersant. 

An aqueous ink jet composition according to the present disclosure includes: C.I. Disperse Red 364 as a first component; a second component which is a dispersant having a chemical structure of at least one of a sulfo group and a salt thereof; and a third component having an indigo skeleton and a chemical structure of at least one of a sulfo group and a salt thereof.

An ink set which is used for sublimation transfer includes a first ink, and a second ink. The first ink has a color after transfer of |a*|&#x2264;10 and |b*|&#x2264;10 in a CIELAB color space, and contains a first disperse dye dispersed by a first dispersion resin. The second ink has a color after transfer of |a*|&#x3e;10 or |b*|&#x3e;10 in the CIELAB color space, and contains a second disperse dye dispersed by a second dispersion resin. A glass transition temperature of the first dispersion resin and is different than that of the second dispersion resin.
