Abstract

New vat dyes containing at least one group of the formula formula wherein a means an aliphatic radical, more conveniently an alkyl radical, in which the ox group is preferably in the beta position with respect to the atom of nitrogen. R means an alkyl group or a radical of the formula -aox and x means an aqueous inorganic acyl radical solubilizing, in particular a radical sulfuric acid. The concept dyes tub, covers the dyes that by reduction can be converted to a form called "leuco" or tub, which shows better affinity for natural or regenerated cellulose fibers than the non-reduced form and which can be oxidized again to the primitive chromophore system. Suitable tub dyes include in particular those of the anthraquinone series, for example containing an unchanged 9,10-dioxoanthracene ring, and in addition anthraquinones which still contain fused carbocyclic juxta rings or which are composed of several anthraquinonic units.
