Abstract
Abstract Anthraquinone compounds represented by the following formula are useful as dyes: ##STR1## wherein Y stands for a hydrogen atom or a nitro group, Z stands for an oxygen or sulfur atom when Y stands for a hydrogen atom, but Z stands for an oxygen atom when Y stands for a nitro group, R 1 stands for a hydrogen atom or a lower alkyl group, R 3 stands for a halogen atom or a group R 2 wherein R 2 stands for an amino, substituted or unsubstituted lower alkylamino, substituted or unsubstituted arylamino, substituted or unsubstituted alkoxy, substituted or unsubstituted aryloxy, substituted or unsubstituted alkylthio, substituted or unsubstituted arylthio group, or a group ##STR2## Q stands for a nitrogen atom or carbon atom bearing a halogen atom when R 3 stands for a halogen atom, but Q stands for a nitrogen atom when R 3 stands for a group R 2 , X stands for a halogen atom, the group ##STR3## links to the benzene ring in the 3'- or 4'-position, and M stands for an alkali metal or hydrogen atom.
