    摘要： Sparingly water-soluble azo compounds of the formula ##STR1## wherein D is phenyl, substituted phenyl, thiazolyl, substituted thiazolyl, benzothiazolyl, substituted benzothiazolyl, 1,3,5-thiadiazolyl, phenyl-1,3,4-thiadiazolyl, nitrobenzoisothiazolyl or substituted thienyl,Wherein each substituent of substituted phenyl, substituted thiazolyl and substituted benzothiazolyl is independently chloro, bromo, nitro, cyano or methylsulfonyl and each substituent of substituted thienyl is independently nitro or acetyl,R.sub.1 is hydrogen, alkyl, alkoxy or --NH--Y--R.sub.5, wherein Y is --CO--, --COO-- or --SO.sub.2 --, and R.sub.5 is alkyl, haloalkyl, phenyl or substituted phenyl,R.sub.2 is hydrogen or alkoxy,R.sub.3 is phenoxyalkyl, substituted phenoxyalkyl, benzyloxyalkyl or substituted benzyloxyalkyl, andR.sub.4 is hydrogen, cyclohexyl, alkyl or alkyl substituted by chloro, bromo or --O--CO--NH--R.sub.6, wherein R.sub.6 is alkyl or phenyl are eminently suitable for application as disperse dyes. From aqueous dispersion such dyes build up powerfully on regenerated fibres and synthetic fibres of high molecular weight and hydrophobic character. Dyeings are obtained which are fast to thermofixation, sublimation, pleating, gas fumes, dry cleaning and wet treatments.

    摘要： Compounds of the formula ##STR1## wherein R.sub.1 is optionally substituted hydrocarbyl (alkyl or phenyl),R.sub.2 is hydrogen, alkyl or acylamino,R.sub.3 is hydrogen, alkyl, substituted alkyl, alkoxy or substituted alkoxy,Each of R.sub.4 and R.sub.5 is independently hydrogen, alkyl or substituted alkyl,T is halo, nitro, cyano, alkyl, alkoxy, alkylsulfonyl, sulfamoyl or alkylsulfamoyl, andn is 0 to 3. These compounds are suitable for the dyeing and printing of textile materials. The dyeings obtained are extremely fast to thermofixation, sublimation, pleating, gas fumes, cross dyeing, rubbing, dry cleaning, chlorine, and wet treatments, such as water, washing and perspiration. The compounds of this invention and other phenylazo-phenyl compounds with an optionally substituted hydrocarbylsulfonyl group (R.sub.1-- SO.sub.2 --) on the diazo component radical in a position ortho to the azo group can be synthesized from the corresponding compounds having a halo atom or nitro group in this position by reaction with a compound of the formula H--SO.sub.2 --R.sub.1 or a salt thereof.
