Carbon black-graft polymer, method for production thereof, and use thereof
 A carbon black-graft polymer, produced by causing a polymer possessing within the molecular unit thereof at least one reactive group selected from the class consisting of aziridine group, oxazoline group. N-hydroxyalkylamide group, epoxy group, and thioepoxy group to react with carbon balck. The polymer can be used as a toner for electrostatically charged image, resin composition, coating composition, ink for thermographic transer, coating gent for magnetic recording medium, rubber composition, and carbon black dispersion and the like.
