DISPERSE AZO DYES, A PROCESS FOR THE PREPARATION THEREOF AND THE USE THEREOF
The present invention relates to azo dyes of formula (1), wherein D is a radical of formula (2) or (3), R.sub.1 and R.sub.2 independently denote hydrogen; C.sub.6-C.sub.10aryl which is unsubstituted or substituted by cyano, carboxy, hydroxy, halogen, C.sub.1-C.sub.6alkyl, or C.sub.1-C.sub.6alkoxy; C.sub.1-C.sub.12alkyl which may be interrupted one or more times by —O—, —S—, —NR.sub.4—, —CO—, —COO— or —OOC—, and is unsubstituted or substituted by cyano, carboxy, hydroxy, C.sub.6-C.sub.10aryl, or C.sub.6-C.sub.10aryloxy, which C.sub.6-C.sub.10aryl or C.sub.6-C.sub.10aryloxy is unsubstituted or substituted by cyano, carboxy, hydroxy, halogen, C.sub.1-C.sub.6alkyl, or C.sub.1-C.sub.6alkoxy; R.sub.3 and R.sub.4 are each independently of the other hydrogen, halogen, nitro, cyano, trifluoromethyl, carboxy, C.sub.1-C.sub.6alkyl, C.sub.1-C.sub.6alkoxy, C.sub.1-C.sub.6alkylcarbonyl, C.sub.6-C.sub.10arylcarbonyl, C.sub.1-C.sub.6alkoxycarbonyl, C—C.sub.6alkylsulfonyl, C.sub.1-C.sub.6alkylsulfonylamino or C.sub.1-C.sub.4alkanoylamino; and R.sub.5 is halogen, nitro, cyano, trifluoromethyl, carboxy, C.sub.1-C.sub.6alkyl, C.sub.1-C.sub.6alkoxy, C.sub.1-C.sub.6alkylcarbonyl, C.sub.6-C.sub.10arylcarbonyl, C.sub.1-C.sub.6alkoxycarbonyl, C.sub.1-C.sub.6alkylsulfonyl, C.sub.1-C.sub.6alkylsulfonylamino or C.sub.1-C.sub.4alkanoylamino; and R.sub.6, R.sub.7, R.sub.8 and R.sub.9 independently of each other are hydrogen, hydroxy, halogen, cyano, nitro or C.sub.1-C.sub.4alkanoylamino, and the radicals X independently denote N or C—H, with the proviso that at least one radical X denotes C—H, which are distinguished by their good lightfastness properties.

Anthraquinone azo dyes
Provided are anthraquinone azo dyes and dye mixtures which are distinguished by a very good build-up capacity and which also yield tinctorially strong dyeings or prints in a golden-yellow to orange shade having all around good properties, especially high temperature light fastness properties. ##STR00001##
