Abstract

An ink jet ink for textile printing contains a reactive dye, where 1.2% by mass or more and 2.3% by mass or less of C.I. Reactive Blue 49 based on the total amount of the ink is contained as the reactive dye.

Claims

1. An ink jet ink for textile printing, comprising

a reactive dye, wherein

1.2% by mass or more and 2.3% by mass or less of C.I. Reactive Blue 49 based on a total amount of the ink is contained as the reactive dye.

2. The ink jet ink for textile printing according to claim 1, wherein

a total content of nickel ions, cobalt ions, and chromium ions in the ink is 10.0 ppm or less based on the total amount of the ink.

3. The ink jet ink for textile printing according to claim 1, further comprising:

a reactive dye having a maximum absorption wavelength of 500.0 nm or more and less than 550.0 nm; and
