Abstract

The invention comprises dyes of the formula <FORM:1044150/C4-C5/1> wherein R1 and R2 are hydrogen, alkyl, haloalkyl or alkoxyalkyl wherein the alkyl radicals may also be linked with each other either directly or via a hetero atom and wherein the nucleus A may contain further substituents. They may be prepared by reacting 1,4-dihydroxy-anthraquinone, its leuco compound or a 1-hydroxy-4 haloanthraquinone with an amino-phenylsulphamate of the formula <FORM:1044150/C4-C5/2> in a molar ratio of about 1:1 in the presence of an acid binding agent.
