| description | A process for producing a charge control agent comprising an azo-based iron complex salt compound as an effective component, comprising steps of:
synthesizing a monoazo compound through diazotization coupling; and
ironing the monoazo compound by using an ironizing agent such as ferric chloride to produce an azo-based iron complex salt compound represented by the following formula.
wherein, p is an integer of 0 to 4, q and s are each an integer of 0 to 5, R 1 to R 3 are each a substituent such as an alkyl group, and A + is a cation. The production process of the present invention is characterized in that the ironization reaction of the monoazo compound is carried out while pH is kept at 7.0 to 8.0. Since the above azo-based iron complex salt compound having high purity can be obtained at a high yield according to the above process, it can be used as a charge control agent directly and a special purification step can be eliminated, thereby making it possible to greatly cut the production cost. |
