   It has also been found that, instead of phosphotungstic acid, other phosphotungstic acids and analogous complex acids such as silicotungstic acid, phosphotungstic acid and the like or their salts can also be used.

The same procedure can be used for laking other basic dyes, e.g. B. of other basic violets, rhodamines, Victoria blue B, diamond green, auramine, etc.
