Azo dyes, dye mixtures, a process for their preparation and a process for dyeing or printing of hydrophobic fiber materials using them

摘要

The present invention relates to the use of these azo dyes and dye mixtures in the dyeing or printing of the formula of an azo dye, and mixtures, semi-synthetic or synthetic hydrophobic fiber materials comprising the azo dyes of two or more structurally different formula. ; Formula 1 ; In the formula 1, ; R ₁ is benzene, naphthalene, diphenyl, azobenzene, thiophene, benzothiazole, benzimidazole isothiazole, thiadiazole, indazole, benzotriazole, pyrazole, anthraquinone, naphthol acid imide, chromones, phthalimide the diazo component radical of the imide or diphenylene oxide series, ; R ₂ is an unsubstituted or substituted aryl radical or unsubstituted or substituted aralkyl radical, ; R ₃ is is optionally substituted with a substituted aryl radical or unsubstituted or substituted aralkyl radical, ; However, one of the substituents R ₂ and R ₃ is a substituted aryl radical is optionally substituted, and excluding the other is unsubstituted or substituted aralkyl radical, a substituted aralkyl radical as 2-hydroxy-2-phenylethyl are do. ; Azo dye, azo dye mixtures, semi-synthetic or synthetic hydrophobic fiber material dyed or printed, three-color dye
