Abstract

Abstract A reactive disazo compound which, in the free acid form, is represented by the formula: ##STR1## wherein R 1 is H, Cl or SO 3 H, R 2 is H, CH 3 or SO 3 H, X is β-sulfatoethyl, β-thiosulfatoethyl, β-phosphatoethyl or vinyl, Y is Cl or F, Z is Cl, F or Z 1 , Z 1 is amino; mono- or dialkylamino having 1 to 4 carbon atoms which may be substituted by hydroxy, carboxy or sulfo; morpholino; anilino which may be substituted by halogen, lower alkyl, lower alkoxy, carboxy or sulfo; N-methylanilino, naphthylamino or sulfo-substituted naphthylamino; alkoxy having 1 to 4 carbon atoms which may be substituted by lower alkoxy; phenoxy; alkylthio having 1 to 4 carbon atoms which may be substituted by hydroxy; phenylthio, and Q is N, C--Cl or C--F when Z is Cl or F and N when Z is Z 1 . These compounds are used for dyeing or printing cellulosic fibers.
