ABSTRACT:
An anthraquinone dye for cellulose-containing fibers having the formula (I) indicated below and a process for producing the same are disclosed: ##STR1## wherein R.sup.1 is an amino group or a hydroxyl group; R.sup.2 is a hydrogen atom, a chlorine atom, a bromine atom, a cyano group or --SO.sub.2 R (wherein R is a lower alkyl group or a phenyl group); R.sup.3 and R.sup.4 are each a hydrogen atom, an amino group, a hydroxyl group, a nitro group, a chlorine atom or a bromine atom; Y is a bonding group --O-- or --S--; one of X.sup.1 and X.sup.2 is a hydrogen atom and the other is ##STR2## (wherein Z is a bonding group --O-- or --S--; R.sup.5 is a lower alkyl group, a lower alkoxy group or a hydrogen atom; R.sup.6 and R.sup.7 are each a hydrogen atom or an alkyl group, an alkenyl group, a cyanohexyl group, an aryl group or an aralkyl group which may be substituted by a cyano group, a hydroxyl group, a lower alkoxy group or a dialkylamino group, or NR.sup.6 R.sup.7 represents a 5- or 6-membered nitrogen-containing heterocyclic ring formed by the bonding of R.sup.6 and R.sup.7 ; the sum of the carbon atoms of R.sup.6 and R.sup.7 is not more than 18); and n is 0 or 1, but n is 0 when X.sup.2 is a hydrogen atom.
