<p>New water-insoluble azo dyes, methods for synthesizing the same, and application of the dyes to textile materials are disclosed. The dyes have the following general formula: (I) wherein: D is the residue of a diazotizable component of the carbocyclic or heterocyclic series and may have substituents such as: halogen; trifluoromethyl; CN; NO2; alkyl C1-C4; NHCO alkyl C1-C4; SO2 alkyl C1-C4; SO2NH2; SO2NH alkyl C1-C4; SO2N (alkyl C1-C4)2; SO2NH phenyl; hydroxyethoxy; chloro-ethoxy; methoxy-ethoxy; COO alkyl C1-C4; COO cycloalkyl; phenyl; phenoxy; phenylazo or naphthylazo; X is an ethylene group, optionally substituted by halogen-methyl, alkyl C1-C4, aryl, aralkyl or CH2OCO(HN)nR (wherein R and n have the meanings defined hereinafter); R is alkyl C1-C8 optionally substituted by halogen, CN,COOH; aryl optionally substituted by one or more atoms of halogen, alkyl C1-C4, alkoxyl C1-C8; aryloxy; aralkoxy; cycloalkoxy; aralkyl; naphtyl optionnally substituted by halogen; alkenyl C2-C8 optionnally substituted by halogen, CN, COOH; R1 and R2, which may be the same or different, may be alkyl C1-C4 optionnally substituted by halogen or CN groups; aralkyl; R3 is H; halogen; alkyl C1-C4; alkoxyl C1-C4; and n is 0 or 1.</p> |
