摘要：
Azo dyes of the formula ##STR1## wherein R.sup.1 is alkyl having 1 to 4 carbon atoms; R.sup.2 is alkyl having 1 to 3 carbon atoms; R.sup.3 is alkylcarbonyloxyethyl having 1 to 3 carbon atoms in the alkyl moiety, alkoxycarbonyloxyethyl having 1 to 4 carbon atoms in the alkoxy moiety, methoxyethoxycarbonyloxyethyl or ethoxyethoxycarbonyloxyethyl; and R.sup.4 is one of the definitions of R.sup.3 or cyanoethyl; or mixtures of at least two species of said formula are used for dyeing and printing hydrophobic fiber materials.
