    • 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".
    • 该专利公开了其中Hal1和Hal2彼此独立地为卤素原子的式“IMAGE”的新型单偶氮化合物和单偶氮化合物的混合物,X为CF 3,CN或SO 2 -A基团,其中A为 取代或未取代的C1-C4烷基或二(C1-C4) - 烷基 - 氨基,其中烷基可以被取代,R是取代或未取代的C1-C4-烷基或取代或未取代的 未取代的C 1 -C 4 - 烷氧基,Y是取代或未取代的C 1 -C 8 - 烷基或取代或未取代的C 3 -C 4 - 烯基,以及它们的制备方法,以及它们作为染色和印花纺织用染料 可用分散染料特别是聚酯材料染色的材料。 特别得到的染色具有非常好的耐光性,亮度,升华坚牢度和免受“催化褪色”的影响。
