[0149] The dispersion liquids 1 to 32 (100 g each) of the Examples and the Comparative Examples were sealed in a glass bottle and left at 60° C. for 14 days. Water was added to each of the dispersion liquids after standing to dilute them 1,000 times, and the volume average particle diameter (D50) was measured using a microtrack UPA (manufactured by Nikkiso Co., Ltd.), and the obtained value was defined as the dispersion liquid particle diameter over time. The evaluation criteria are as follows. Rank 2 and below are practically unacceptable levels.

—Evaluation Criteria—

Also, the dispersion liquids 1 to 32 (100 g each) were sealed in glass bottles and left at 60° C. for 14 days. Water was added to each of the dispersion liquids after standing and diluted 10,000 times, and an absorbance at the maximum absorption wavelength was similarly measured.

[Evaluation of Ink]

[0158] The ink storage stability was evaluated for the inks 1 to 32 obtained as described above by the following evaluation method. Results are shown in Tables 6 to 10 above.

(Ink Storage Stability)

[0159] Water was added to each of the inks 1 to 32 of the Examples and the Comparative Examples to dilute them 10,000 times, and an absorbance at the maximum absorption wavelength at 400 to 780 nm was measured. Inks 1 to 32 (100 g each) were also sealed in glass bottles and left at 60° C. for 14 days. Water was added to the inks 1 to 32 after standing and diluted 10,000 times, and an absorbance at the maximum absorption wavelength was measured in the same manner. The absorbance after standing was calculated regarding the absorbance before standing as 100%, and the obtained value was used to evaluate the storage stability of the ink. The evaluation criteria are as follows. Rank 2 and below are practically unacceptable levels.

—Evaluation Criteria—

[0160] Rank 5: The absorbance after standing is 95% or more.
Rank 4: The absorbance after standing is 90% or more and less than 95%.
Rank 3: The absorbance after standing is 80% or more and less than 90%.
Rank 2: The absorbance after standing is 60% or more and less than 80%.
Rank 1: The absorbance after standing is less than 60%.

[0161] From the results of Tables 6 to 10 above, it is apparent that the inks 1 to 21 of the Examples are inks having excellent storage stability.

[Preparation of Dyed Fabric]

[0162] Using the inks 1 to 21 of the Examples shown in Tables 6 to 8 above, a solid pattern was printed on a transfer paper, which is an intermediate recording medium, by an ink-jet printer (manufactured by Seiko Epson Co., Ltd., PX-105). An adhered portion of the ink in this printed transfer paper was cut into 35 cm×40 cm. After superimposing an ink adhering surface of the transfer paper after cutting and polyester fabric (pongee) having the same size, heat treatment was performed using a transfer press machine (manufactured by Solar Seiki Co., Ltd., TP-600A2) under a condition of 200° C. for 60 seconds, and sublimation transfer dyeing was performed from the transfer paper to the polyester fabric. As a result, respective pieces of polyester fabric could obtain the desired color.
