An ink jet ink composition contains a disperse dye, and a compound represented by the following formula (1): ##STR00001##
In the formula, Ar.sub.1 and Ar.sub.2 each independently represent an aryl group; R.sub.1 and R.sub.2 each independently represent a chemical species selected from the group consisting of hydrogen, alkyl groups having a carbon number of 1 to 3, a sulfo group, —O—SO.sub.3H, a carboxy group, and a hydroxy group; and n's each independently represent an integer of 0 to 5. The content of the compound represented by formula (1) is 0.1% by mass to 20% by mass relative to the total mass of the ink jet ink composition.

A black inkjet ink composition includes a carbon black pigment; a dispersion synergist having an aromatic structure substituted with at least one solubilizing moiety selected from the group consisting of an ionic moiety, a non-ionic moiety, and a combination thereof; a polar solvent; and water. A method for making the black inkjet ink composition and a printing method using the same is also disclosed.

A sprayable and hygroscopic ink for a digital printing process on a fabric includes 3.0 parts by weight to 6.0 parts by weight of a colorant, 0.5 parts by weight to 2.0 parts by weight of a hygroscopic agent, 0.5 parts by weight to 1.0 part by weight of a surfactant, and a balance of a solvent, in which a pH value of the hygroscopic agent is between 6.0 and 8.5 at 25° C., and a particle diameter D90 of the sprayable and hygroscopic ink is between 180 nm and 220 nm.

Provided is an inkjet composition for printing an indelible colorant onto a substrate. Also provided is a method of printing using the inkjet composition, and a printed substrate obtainable and obtained from the method of printing. The inkjet composition has an indelible colorant, one or more solvents, and a binder. The migration distance of the indelible colorant in the substrate is less than 0.85 mm after 7 days at 25° C. The composition may be used to provide indelible markings in the surface of the substrate, and these markings do not significantly disperse over time.
