PROBLEM TO BE SOLVED: To provide a process for preparing carbon black subjected to adsorption treatment with an organic dyestuff derivative or triazine derivative excellent in dispersion stability. SOLUTION: The process for preparing carbon black subjected to adsorption treatment comprises subjecting, to adsorption treatment in water, an organic dyestuff derivative or a triazine derivative and carbon black in such an amount that the adsorption area is 50% or more of the BET specific surface area of the carbon black, under assumption that the organic dyestuff skeleton of the dyestuff derivative or the triazine moiety of the triazine derivative is an adsorption site. The dyestuff and triazine derivatives have acidic or basic functional groups. COPYRIGHT: (C)2004,JPO&NCIPI
