Carbon black-graft polymer, its production and use.

摘要

A carbon black-graft polymer, produced by causing a polymer possessing within its molecular unit at least one reactive group which is an aziridine group, oxazoline group, N-hydroxyalkylamide group, epoxy group or thioepoxy group to react with carbon black. The polymer can be used for example as a toner for an electrostatically charged image, a resin composition, a coating composition, an ink for thermographic transfer, a coating agent for a magnetic recording medium, a rubber composition and as a carbon black dispersion.
