Ink 27 was prepared with reference to Example 1 of Patent Literature 4 (Japanese Patent Application Laid-Open No. 2010-018741). A mixture of 20.0 parts of carbon black (trade name: Monarch (M) 1000, product of Cabot), 12.0 parts of a polymer dispersant (trade name: BYK190, product of BYK Japan) and 68.0 parts of ion-exchanged water was treated by a Nano mill in which the packing rate of zirconia beads having a diameter of 0.5 mm was set to 80%, thereby preparing a pigment dispersion having a pigment content of 20 mass %. Fifteen parts of the resultant pigment dispersion, 10.0 part of a water-soluble polyurethane polymer (trade name: SF126, product of DAI-ICHI KOGYO SEIYAKU), 30.0 parts of diethylene glycol methyl ethyl ether, 0.2 parts of a silicone compound (trade name: FZ-2105, product of Dow Corning Toray), 0.4 parts of a stabilizer (trade name: ADEKA PLURONIC F-108, product of ADEKA) and 44.4 parts of ion-exchanged water were mixed, sufficiently stirred and dispersed, and the resultant dispersion was then filtered under pressure through a microfilter (product of Fuji Photo Film Co., Ltd.) having a pore size of 3.0 μm to prepare Ink 27.
