ABSTRACT:
The patent discloses novel monoazo compounds, and mixtures of monoazo compounds, of the formula ##STR1## in which Hal.sub.1 and Hal.sub.2 independently of one another are each a halogen atom, X is a CF.sub.3, CN or SO.sub.2 --A group, in which A is a substituted or unsubstituted C.sub.1 -C.sub.4 -alkyl group or a di-(C.sub.1 -C.sub.4)-alkyl-amino group, in which the alkyl radicals can be substituted, R is a substituted or unsubstituted C.sub.1 -C.sub.4 -alkyl group or a substituted or unsubstituted C.sub.1 -C.sub.4 -alkoxy group and Y is a substituted or unsubstituted C.sub.1 -C.sub.8 -alkyl group or a substituted or unsubstituted C.sub.3 -C.sub.4 -alkenyl group, as well as processes for their preparation, and their use as dyes for dyeing and printing textile materials which are dyeable with disperse dyes, especially polyester materials. The dyeings obtained in particular have very good light fastness, brilliance, sublimation fastness and freedom from "catalytic fading".
