摘要： A carbon black aqueous dispersion which has excellent dispersibility and ink performance and is suitable as an aqueous black ink for an inkjet printer or the like, and a method of producing the same. The carbon black aqueous dispersion is obtained by spraying a slurry including carbon black, a surface chemical modifier, and an aqueous medium under pressure from a nozzle to cause collision between sprayed streams or between sprayed streams and a wall surface. The carbon black agglomerates have a maximum particle diameter of 1 µm or less. The production method includes mixing carbon black and a surface chemical modifier into an aqueous medium to form a slurry, and spraying the slurry from a nozzle under pressure to cause collision between sprayed streams or between sprayed streams and a wall surface to atomize and chemically modify carbon black agglomerates, thereby finely dispersing the carbon black in the aqueous medium to such an extent that the carbon black agglomerates have a maximum particle diameter of 1 µm or less.

摘要： A carbon black aqueous pigment which exhibits excellent water-dispersibility and ink performance, and a method of producing a carbon black aqueous dispersion are disclosed. The carbon black aqueous pigment includes carbon black A having a specific surface area by nitrogen adsorption of 150 m 2 /g or more, a DBP absorption of 95 cm 3 /100 g or more, and a tinting strength of 120% or more, and carbon black B having a specific surface area by nitrogen adsorption of less than 150 m 2 /g, a DBP absorption of less than 95 cm 3 /100 g, and a tinting strength of 120% or more, the carbon black A and the carbon black B being subjected to surface oxidation and neutralization, at least the carbon black A being atomized, and the carbon black A and the carbon black B being mixed in a weight ratio of 20:80 to 80:20. The method includes oxidizing the carbon black A and the carbon black B individually in an oxidizing agent aqueous solution, followed by neutralization, atomizing at least the carbon black A, purifying the carbon black A and the carbon black B, mixing the carbon black A and the carbon black B in a weight ratio of 20:80 to 80:20, and dispersing the mixture in an aqueous medium.
