PROBLEM TO BE SOLVED: To provide a novel carbon black composite polymer having a high carbon black content, excellent dispersibility in various target media, excellent electrical insulation, and light or heat sensitivity. SOLUTION: A carbon black is a block or graft polymer comprising a segment (A) having an amino group, an amide group and / or a nitrile group, and a segment (B) having a different structure from the segment (A). In a carbon black composite polymer obtained by mixing and dispersing, in the final form as a carbon black composite polymer, the segments (A) and / or (B) are formed by a matrix of a target medium in which the carbon black composite polymer is blended. A carbon black composite polymer having a reactive group (II). |
