METHOD FOR PRODUCING SELF-DISPERSIBLE TYPE CARBON BLACK

摘要

PROBLEM TO BE SOLVED: To provide a method for producing self-dispersible type carbon black which produces a self-dispersible type carbon black by reacting a water-soluble compound having at least an azo group, and an aryl group or a heteroaryl group which is substituted with an unsubstituted amino group in the molecule or a salt thereof, or a mixture thereof, with carbon black.;SOLUTION: There is provided a method for producing self-dispersible type carbon black which diazotizes an unsubstituted amino group of a compound having at least an azo group, and an aryl group or a heteroaryl group which is substituted with the unsubstituted amino group or a salt thereof, or a mixture thereof, and then reacting the diazotized substance with carbon black.;SELECTED DRAWING: None;COPYRIGHT: (C)2016,JPO&INPIT
