Abstract

The present invention relates to 2-phenoxy or 2-phenylthio anthraquinone compounds which bear a group of formula VI, ##STR1## bound to the para position of the phenoxy or phenylthio group, IN WHICH R.sub.3 is hydrogen; (C.sub.1-6)alkyl; (C.sub.1-3)alkyl monosubstituted by hydroxyl, cyano, (C.sub.1-2)alkylcarbonyloxy, (C.sub.1-2)alkoxycarbonyl or (C.sub.1-2)alkoxycarbonyloxy; (C.sub.2-6)alkenyl; phenyl; or tolyl; PA0 R.sub.4 is --(CH.sub.2).sub.n -- or --CH(R.sub.10)--, PA0 R.sub.5 is (C.sub.2-6)alkylene;--R.sub.11 --O--R.sub.12 -- or --CH.sub.2 CH.sub.2 --0--CH.sub.2 CH.sub.2 --O--CH.sub.2 CH.sub.2 --, PA0 R.sub.6a is (C.sub.1-12)alkyl; (C.sub.1-12)alkyl monosubstituted by chlorine, bromine or hydroxyl; unsubstituted phenyl(C.sub.1-2)-alkyl, (C.sub.5-7)cycloalkyl or phenyl; or phenyl or phenyl(C.sub.1-2)alkyl in which the phenyl ring is monosubstituted by chlorine, bromine or methyl, PA0 R.sub.10 is (C.sub.1-6)alkyl or phenyl, PA0 Each of R.sub.11 and R.sub.12, independently, is (C.sub.2-6) alkylene, PA0 M is 0 or 1, and PA0 N is 1, 2, 3, 4 or 5, which compounds are useful as disperse dyestuffs for dyeing or printing substrates dyeable with disperse dyes, especially linear aromatic…
