WATER-INSOLUBLE SULFUR DYE, ITS PRODUCTION AND METHOD OF USING IT

The water-insoluble dyes of the formula I in which e.g. F is the dye chromophore of C.I. Leuco Sulphur Black 1, R is hydrogen or alkyl, M is a quaternary ammonium or phosphonium cation in which the sum of the carbon atoms in the hydrophobic radicals present is at least 6, and n is a number such that...

Beschreibung
Zusammenfassung:	The water-insoluble dyes of the formula I in which e.g. F is the dye chromophore of C.I. Leuco Sulphur Black 1, R is hydrogen or alkyl, M is a quaternary ammonium or phosphonium cation in which the sum of the carbon atoms in the hydrophobic radicals present is at least 6, and n is a number such that the dye I contains from 5 to 20% by weight of -COO groups, are suitable in particular for the production of recording fluids.
