Abstract

The invention discloses a 5-chloronitroaniline-containing azoic compound as well as a preparation method and an application thereof. The 5-chloronitroaniline-containing azoic compound is as shown in a formula (I), wherein each group is defined in the specification. A dye containing the 5-chloronitroaniline-containing azoic compound is used for dyeing polyesters, terylenes, terylene superfine fibers and blended fabrics of the terylene superfine fibers and polyurethanes, and has the advantages of excellent washing resistance, friction resistance, light resistance and sublimation fastness.

Description

A technical field [0001] The invention relates to an azo compound containing 5-chloronitroaniline, a preparation method and an application thereof, and belongs to the technical field of chemical material preparation. Two background technology [0002] 2,4-dinitro-6-bromo (or chloro) aniline is used as a disperse dye of the diazo component of the dye, mostly dark varieties, widely used in polyester, polyester and other fabrics, such as C.I. Disperse Blue 79:1 , Disperse Blue 291, Disperse Violet 93, etc. However, they have poor washing fastness and are difficult to dye deep, especially in the case of polyester and spandex blends, it is even more difficult to dye deep, and the washing fastness is even worse. Therefore, there is a need for an economical new dye with good depth and high wash fastness. Three invention content [0003] The object of the present invention is to provide a kind of azo compound containing 5-chloronitroaniline, which has excellent deep color dyeing...
