The present invention relates to azo dyes of formula
wherein
R1 denotes C1-C12 alkyl which is unsubstituted or substituted by one or more C1-C12 alkoxy groups, hydroxyl groups, amino groups, cyano groups or halogen atoms and which may be interrupted one or more times by the radical —O—, —S—, —NR4—, —COO— or —OOC—;
R4 is hydrogen or C1-C12 alkyl;
either R2 is cyano and R3 is halogen or R2 is halogen and R3 is cyano; and
Ar represents a carbocyclic or heterocyclic aromatic radical,
to the process for the preparation thereof, to mixtures containing said dyes and to the use thereof in dyeing or printing semi-synthetic and especially synthetic hydrophobic fiber materials, more especially textile materials.
本发明涉及式如下的偶氮染料
式中
R1 表示未被取代或被一个或多个 C1-C12 烷氧基、羟基、氨基、氰基或卤素原子取代的 C1-C12 烷基,且可被基团 -O-、-S-、-NR4-、-COO- 或 -OOC- 中断一次或多次;
R4 是氢或 C1-C12 烷基;
R2 是氰基,R3 是卤素,或者 R2 是卤素,R3 是氰基;以及
Ar 代表碳环或杂环芳香基、
其制备工艺,含有上述染料的混合物,以及其在半合成,特别是合成疏水性纤维材料,尤其是纺织材料的染色或印花中的用途。
