摘要:
An inkjet recording ink including: water; a first pigment dispersion; a second pigment dispersion; and a penetrating agent, wherein the first pigment dispersion includes oxidized carbon black CB-1 dispersed therein with a pH of the first pigment dispersion adjusted to 6 to 8 with an alkali metal hydroxide, where the oxidized carbon black CB-1 is oxidized with ozone and has a volatile content of 10% to 20% and a BET specific surface area of 90 m2/g to 150 m2/g, and the second pigment dispersion includes carbon black CB-2 dispersed therein with a naphthalene sulfonic acid-formalin condensate, where the carbon black CB-2 has an average particle diameter (D50) of 50 nm to 180 nm as measured by a dynamic light scattering method and a standard deviation of particle diameters of the carbon black CB-2 is equal to or lower than ½ of the average particle diameter.
