Dyeing cellulose-containing textile material with hydrogenated indigo

Polycyclic vat dyes of the general formula I ##STR1## where X is hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -alkoxy, halogen or nitro, obtainable by reacting (9)-benzo-5-aminoanthraquinonyl(2,1-h)-8-azapyrenone-3(II) ##STR2## with a benzoyl chloride of the formula III ##STR3## in a dipolar aprotic solvent.

Polycyclic vat dyes

Continuous production of surface dyeings on cellulose fiber textile

An improved process for dyeing or printing water-swellable cellulosic fibers and mixtures of said cellulosic fibers with synthetic fibers by contacting the fibers throughout with a dye liquor or print paste which contains, as essential ingredients, water in an amount sufficient to swell the cellulosic fibers, a water-insoluble disperse dye and a water-soluble solvent which maintains swelling of the cellulose if water is removed and which is a solvent for the disperse dye, and heating the contacted fibers to effect fixation of the dye, the improvement comprising using as water-soluble solvent a mixture of
