Abstract

An ink jet textile printing composition set of the invention includes an ink jet textile printing ink composition and a penetrant. The ink jet textile printing ink composition contains a fluorescent dye and water, and the penetrant contains a compound having a lactam structure and water.

Claims (36)

1. An ink jet textile printing composition set comprising:

an ink jet textile printing ink composition and a penetrant,

wherein the ink jet textile printing ink composition contains a fluorescent dye and water,

a content of the fluorescent dye is 0.8% by mass or more and 5.0% by mass or less based on a total mass of the ink jet textile printing ink composition, and

the penetrant contains a compound having a lactam structure and water.

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

a content of the compound having the lactam structure is 5.0% by mass or more based on a total mass of the penetrant.

3. The ink jet textile printing composition set according to claim 1 , wherein

the compound having the lactam structure contains 2-pyrrolidone or N-methyl-2-pyrrolidone.

4. The ink jet textile printing composition set according to claim 1 , wherein

the fluorescent dye is an acidic dye.

5. The ink jet textile printing composition set according to claim 1 , wherein

the fluorescent dye contains one or more selected from C.I. Acid Yellow 184, C.I. Acid Yellow 250, C.I. Acid Yellow 73, C.I. Acid Red 52, C.I. Acid Red 74, and C.I. Acid Red 289.

6. The ink jet textile printing composition set according to claim 1 , wherein

the ink jet textile printing ink composition contains one or more selected from an Na ion, a K ion, and an Li ion, and

a total content of the Na ion, the K ion, and the Li ion is 100 ppm or more and 8000 ppm or less.

7. An ink jet textile printing method, which is a recording method that performs printing using the ink jet textile printing ink composition and the penetrant according to claim 1 , the method comprising:
