Abstract: A carbon black capable of floating on a surface of a pure water when the carbon black is shaken together with the pure water at 25° C., and settling from the surface of the pure water at 50° C. or higher when the temperature of the pure water is increased stepwise from 25° C. and the carbon black is shaken together with the pure water at each temperature.
