摘要： Dyes of the formula ##STR1## wherein R.sub.1 is a carbocyclic or heterocyclic diazo component radical,R.sub.2 is cyano or acyl,R.sub.3 is alkyl, carbocyclic aryl or heterocyclyl, or a substituted deriive thereof, andR.sub.4 is hydrocarbyl or substituted hydrocarbyl, with the proviso that R.sub.4 is free of sulfo groups and protonizable groups, are useful as disperse dyes for the dyeing and printing of fibres and textiles of synthetic and semi-synthetic, hydrophobic organic substances of high molecular weight. These dyes build up excellently and yield dyeings which are fast to thermofixation, sublimation, pleating, ozone, rubbing, gas fumes, water, sea water, perspiration, alkali and washing.
