[Formula] (In the formula, Y 1 and Y 2 are as defined above.) By coupling with the azo component represented by the following conventional method, the following general formula (In the formula, Y 1 , Y 2 , n and n' are as defined above.) A monoazo compound represented by the formula is synthesized, and then this monoazo compound is chromated by a conventional method in water or an organic solvent. It can be obtained in high yield by heat treatment with an imparting agent or a cobaltization imparting agent. Note that, since the metal complex salt compound of the present invention is asymmetric, it is a condition that the monoazo compound of the general formula (4) and the monoazo compound of the general formula (5) are not the same in the complex salt formation reaction. Examples of the diazo component represented by the above general formula (2) used in the present invention include 5-nitro-2-aminophenol, 4,
Examples include 6-dinitro-2-aminophenol. Further, examples of the azo component represented by the above general formula (3) include 2-naphthol, 3-hydroxy-2-naphthoanilide, 3-hydroxy-4'-
Chloro-2-naphthanilide, 3-hydroxy-
2-Naphtho-p-anisidite, 3-hydroxy-2-naphtho-o-anisidite, 3-hydroxy-2-naphtho-o-phenethide, 3-hydroxy-2',5'-dimethoxy-2-naphthanilide, 3- Hydroxy-2-naphtho-o-toluidite, 3-hydroxy-2-naphtho-2'4'-xylidite, 3-hydroxy-3'-nitro-2-naphthoanilide, 3-hydroxy-4'-chloro-2
-naphtho-o-toluizite, 3-hydroxy-
Examples include 2',4'-dimethoxy-5'-chloro-2-naphthoanilide. A second invention of the present invention is an electrophotographic toner containing an asymmetric metal complex compound represented by the above general formula (1). Regarding electrophotographic toners containing metal complex compounds, for example, Japanese Patent Publication No. 1973-20153, Japanese Patent Publication No. 43
-17955 and Japanese Patent Publication No. 43-27596, etc., the toner containing the asymmetric metal complex compound represented by the general formula (1) of the present invention is more electrostatically charged than those described in these publications. It also shows negative results in mutagenicity test (Ames test). Further, the compound of the present invention has an extremely low bulk specific gravity and an extremely large surface area, and is therefore suitable as an electrophotographic toner. Furthermore, since the metal complex compound of the present invention has excellent heat resistance, water resistance, and light resistance, it can be suitably used as a coloring agent for various resins and as a paint for woodworking and the like. Hereinafter, the present invention will be explained in detail with reference to Examples, where parts are parts by weight. Example 1 19.9 parts of 4,6-dinitro-2-aminophenol was stirred with 26 parts of concentrated hydrochloric acid and 400 parts of water, cooled on ice to 0-5°C, and added with sodium nitrite.
6.9 parts were added and stirred at the same temperature for 2 hours to diazotize. This diazotide was mixed with 300 parts of water at 0 to 5°C, and 10
After a coupling reaction, a motoazo compound having the following structural formula was isolated. This monoazo compound paste was dissolved in 150 parts of ethylene glycol, 20 parts of concentrated acid and
Add 9.2 parts of 40% chromium sulfate aqueous solution and heat to 95-105℃
The mixture was stirred for 3 hours to perform chromization. Next, 52 parts of a monoazo compound having the following structure obtained according to the above method Add 20 parts of sodium hydroxide and heat to 95-100℃
I stirred it for 2 hours. Cool the contents to room temperature,
Add 10 parts of hydrochloric acid to make a combined acid, isolate the product by filtration at room temperature, and dry under reduced pressure at 50 to 60°C to obtain a fine black powder of a chromium complex compound represented by the following formula.
Obtained 105 copies. When this chromium complex salt compound was dissolved in dimethylformamide, it exhibited a black color (maximum absorption wavelength 575 nm). When this chromium complex compound was used as a coloring and charge control agent for electrophotographic toner, it was possible to obtain clear images without fogging and stable copied images that did not change even after repeated use over a long period of time. Ta. When used as a coloring agent for polystyrene, polyester, and polyethylene resins, a black colored resin with excellent water resistance and light resistance and a clear color tone could be obtained. Thereafter, an asymmetric metal complex compound was obtained in the same manner as in this example.
