- 摘要：
A method for producing a surface-treated carbon black particle aqueous dispersion that exhibits excellent blackness and dispersibility, exhibits excellent storage stability, suppresses feathering, exhibits an excellent discharge capability and rubfastness (quick-drying capability), and suppresses metal corrosion when used in an aqueous black pigment(colorant) ink, is disclosed. The method for producing a surface-treated carbon black particle aqueous dispersion includes providing an aqueous dispersion of oxidized carbon black particles obtained by forming acidic hydroxyl groups on a surface of carbon black particles having a DBP absorption of 120 cm 3 /100 g or more, neutralizing 5% or more and less than 50% of the acidic hydroxyl groups with a polyvalent cation, and neutralizing the remainder of the acidic hydroxyl groups with a monovalent cation.
