2. Evaluation of Stock Solution for Ink-Jet Ink Production

2-1. Change in Particle Diameter

[0153] After the average particle diameter of the dye immediately after the production and the average particle diameter of the dye which was contained in a predetermined container and was then left for one week in an environment at 60 C. were obtained from the stock solution for ink-jet ink production of each of Examples and Comparative Examples, from the values thus obtained, the rate of change in the average particle diameter of the dye which was left for one week in an environment at 60 C. to the average particle diameter of the dye immediately after the production was obtained, and evaluation was performed in accordance with the following criteria. In addition, in Examples A1 to A35 and Comparative Examples A2 to A5, the dye was used as a dye, the average particle diameter of which was to be measured, and in Comparative Example Al, C.I. Disperse Yellow 54 was used as a dye, the average particle diameter of which was to be measured. In addition, for the measurement of the average particle diameter, a Microtrac UPA (manufactured by Nikkiso Co., Ltd.) was used. It can be said that as the rate of change in the average particle diameter is increased, the storage stability is degraded.

[0154] A: Rate of change in average particle diameter of less than 5%.

[0155] B: Rate of change in average particle diameter of 5% to less than 10%.

[0156] C: Rate of change in average particle diameter of 10% to less than 15%.

[0157] D: Rate of change in average particle diameter of 15% to less than 20%.

[0158] E: Rate of change in average particle diameter of 20% or more.

2-2. Generation of Foreign Materials

[0159] The stock solution for ink-jet ink production of each of Examples and Comparative Examples in an amount of 10 mL was received in a predetermined glass bottle so that a gas-liquid interface existed and was then left for five days in an environment at 60 C. Subsequently, after the stock solution for ink-jet ink production was filtrated by a metal mesh filter having an opening diameter of 10 m, the number of solid materials remaining on the metal mesh filer per square millimeter was counted, and evaluation was performed in accordance with the following criteria. It can be said that as the amount of foreign materials thus generated is increased, the storage stability is degraded.

[0160] A: The number of solid materials per square millimeter is less than 5.

[0161] B: The number of solid materials per square millimeter is 5 to less than 10.

[0162] C: The number of solid materials per square millimeter is 10 to less than 30.

[0163] D: The number of solid materials per square millimeter is 30 to less than 50.

[0164] E: The number of solid materials per square millimeter is 50 or more.

[0165] Those results are collectively shown in Tables 5 and 6.

4. Evaluation of Ink-Jet Ink

4-1. Change in Particle Diameter

[0172] After the average particle diameter of the dye immediately after the production and the average particle diameter of the dye which was contained in a predetermined ink container and was then left for one week in an environment at 60 C. were obtained from the ink-jet ink of each of Examples and Comparative Examples, from the values thus obtained, the rate of change in the average particle diameter of the dye which was left for one week in an environment at 60 C. to the average particle diameter of the dye immediately after the production was obtained, and evaluation was performed in accordance with the following criteria. In Examples B1 to B38 and Comparative Examples B2 to B5, the dye was used as a dye, the average particle diameter of which was to be measured, and in Comparative Example B1, C.I. Disperse Yellow 54 was used as a dye, the average particle diameter of which was to be measured. In addition, for the measurement of the average particle diameter, a Microtrac UPA (manufactured by Nikkiso Co., Ltd.) was used. It can be said that as the rate of change in the average particle diameter is increased, the storage stability is degraded.

[0173] A: Rate of change in average particle diameter of less than 5%.

[0174] B: Rate of change in average particle diameter of 5% to less than 10%.

[0175] C: Rate of change in average particle diameter of 10% to less than 15%.

[0176] D: Rate of change in average particle diameter of 15% to less than 20%.

[0177] E: Rate of change in average particle diameter of 20% or more.

4-2. Generation of Foreign Materials

[0178] The ink-jet ink of each of Examples and Comparative Examples in an amount of 10 mL was received in a predetermined glass bottle so that a gas-liquid interface existed and was then left for five days in an environment at 60 C. Subsequently, after the ink-jet ink was filtrated by a metal mesh filter having an opening diameter of 10 m, the number of solid materials remaining on the metal mesh filer per square millimeter was counted, and evaluation was performed in accordance with the following criteria. It can be said that as the amount of foreign materials thus generated is increased, the storage stability is degraded.

[0179] A: The number of solid materials per square millimeter is less than 5.

[0180] B: The number of solid materials per square millimeter is 5 to less than 10.

[0181] C: The number of solid materials per square millimeter is 10 to less than 30.

[0182] D: The number of solid materials per square millimeter is 30 to less than 50.

[0183] E: The number of solid materials per square millimeter is 50 or more.

4-3. Ejection Stability by Ink Jet Method

[0184] The ink-jet ink of each of Examples and Comparative Examples was filled in a predetermined ink container and was then left for five days in an environment at 60 C.

[0185] Subsequently, after the container described above was fitted to a recording apparatus PX-H6000 (manufactured by Seiko Epson Corporation), the ink-jet ink was ejected, so that a solid pattern was adhered to TRANSJET Classic (manufactured by Cham Paper) functioning as an intermediate transfer medium at a recording resolution of 1,440720 dpi. In addition, the operation environment of the recording apparatus was set to a temperature of 40 C. and a relative humidity of 20%.

[0186] The number of missing nozzles was investigated when the solid pattern was formed on 30 intermediate transfer media, and evaluation was performed in accordance with the following criteria. It can be said that as the number of missing nozzles is increased, the ejection stability is degraded.

[0187] A: The number of missing nozzles is zero.

[0188] B: The number of missing nozzles is 1 to 9.

[0189] C: The number of missing nozzles is 10 to 19.

[0190] D: The number of missing nozzles is 20 to 29.

[0191] E: The number of missing nozzles is 30 or more.

[0192] In addition, the ink container of PX-H6000 manufactured by Seiko Epson Corporation has an ink charge port through which the aqueous ink jet composition can be replenished and is opened to the air when the ink container is fitted to the recording apparatus in a ready to use state.

4-4. Clogging Recovery Property

[0193] After the ink-jet ink of each of Examples and Comparative Examples was filled in a predetermined container, this container was fitted to PX-H6000 manufactured by Seiko Epson Corporation.

[0194] After normal ejection from all nozzles was confirmed, the recording apparatus under the normal condition was placed in an Off state and was then left for one month in an environment at 40 C.

[0195] Subsequently, the number of recovery operations performed by suction until the normal ejection was recovered was obtained, and evaluation was performed in accordance with the following criteria.

[0196] A: Normal ejection is performed by one to three recovery operations.

[0197] B: Normal ejection is performed by four to six recovery operations.

[0198] C: Normal ejection is performed by seven to nine recovery operations.

[0199] D: After nine recovery operations are performed, the apparatus is left at room temperature for 12 hours, and normal ejection is then performed by additional one to three recovery operations.

[0200] E: After nine recovery operations are performed, the apparatus is left at room temperature for 12 hours, and normal ejection is still not performed by additional three recovery operations.

4-5. Coloring Property

[0201] After one side of the 30.sup.th intermediate transfer medium to which the ink-jet ink was adhered in the above 4-3 on which the aqueous ink jet composition was adhered was closely brought into contact with a cloth (100% of a polyester, Amina, manufactured by Toray Industries, Inc.) which was a white recording medium, and in the state described above, by using a heat press machine (TP-608M, manufactured by Taiyo Seiki Co., Ltd.), sublimation transfer was performed by heating at 180 C. for 60 seconds, so that a recorded matter was obtained.

[0202] Evaluation of the coloring property of the recorded matter thus obtained was performed. In particular, after the optical density (OD) value of the recorded matter thus obtained was measured using a colorimeter (Gretag Macbeth Spectrolino, manufactured by X-Rite), evaluation was performed in accordance with the following criteria. It can be said that as the OD value is decreased, the coloring property is degraded.

[0203] A: OD value of 1.50 or more.

[0204] B: OD value of 1.45 to less than 1.50.

[0205] C: OD value of 1.40 to less than 1.45.

[0206] D: OD value of 1.35 to less than 1.40.

[0207] E: OD value of less than 1.35.

[0208] Those results are collectively shown in Tables 9 and 10.
