| use | is mainly used for dyeing cellulose fibers such as cotton and viscose, as well as for dyeing paper, biological dyeing and film film, and also for preparing ink. Direct lake blue 5B is one of the main blue dye varieties currently used, and it is used in viscose fabrics for dyeing and printing. In addition to being used alone, it is often matched with direct dyes such as green B, dark green B, bordeaux GB, dark brown M and copper blue 2R. It is used for dyeing cotton, hemp, silk, nylon, viscose and other fibers, and can also be used for coloring leather and pulp |
| production method | is obtained by diazotization of o-(II) anisidine (3,3 '-dimethoxybenzidine) with sodium nitrite and sulfuric acid, then coupling with h acid under alkaline conditions, and then salting out, filtering and drying.
