PROBLEM TO BE SOLVED: To provide a dispersant for carbon black, capable of dispersing carbon black to various mediums such as solvent, resin and rubber.SOLUTION: A dispersant for carbon black contains a polyoxyalkylene amine compound (A) represented by general formula (1). A carbon black dispersion containing the dispersant, carbon black and a dispersion medium; and a method for producing the dispersant are also provided. [In the formula, Z is a residue obtained by removing p primary amino groups and n active hydrogens from an amine compound (a), AO is 2-4C alkylene oxy, m, which shows the average addition mole number of the alkylene oxy, is a number of 1-100, n is an integer of 1-5, and p is an integer of 1-3]. |
