Process for producing black pigment |
| abstract |
A process for producing an aniline black in which harmful substances such as chromium and copper are not used and hence there is no fear that such harmful substances come into the product; and a novel aniline black which is obtained by the process and is not inferior in properties to the aniline black obtained by the chromium process. The process of the invention is characterized by oxidizing aniline with a persulfate in an aqueous acid solution. Also provided are a printing ink composition, a coating composition, and a black pigment for liquid-crystal displays, each of which contains or comprises the aniline black obtained by the process. |
