Abstract

The ink composition for ink jet textile printing according to the invention is an ink composition which includes each dye satisfying the following conditions A, B, and C, two or more kinds of solvent having a boiling point of 190° C. or higher and lower than 260° C. under a pressure of 1 atm, and water, in which the solvent includes 5% by mass or greater of a nitrogen-containing heterocyclic compound with respect to the total mass of the ink composition and 5% by mass or greater of an alkyl polyol with respect to the total mass of the ink composition.
A: Maximum absorption wavelength is in a range of 550 nm and 750 nm B: Maximum absorption wavelength is in a range of 450 nm or greater and less than 500 nm C: Maximum absorption wavelength is in a range of 400 nm or greater and less than 450 nm.

First claim

water,
wherein the solvent includes 5% by mass to 15% by mass of a nitrogen-containing heterocyclic compound with respect to the total mass of the ink composition and 5% by mass or greater of an alkyl polyol with respect to the total mass of the ink composition;
A: Maximum absorption wavelength is in a range of 550 nm to 750 nm
B: Maximum absorption wavelength is in a range of 450 nm or greater and less than 500 nm
C: Maximum absorption wavelength is in a range of 400 nm or greater and less than 450 nm.

2. The ink composition for ink jet textile printing according to claim 1 ,
wherein the dye satisfying the condition A includes at least one kind of C. I. Reactive Black 39, C. I. Reactive Blue 49, and C. I. Reactive Blue 72,
