Abstract
Abstract Dyes of the formula ##STR1## where Y is alkyl of 3 to 18 carbon atoms or phenyl which is unsubstituted or substituted by chlorine, bromine, alkoxy of 1 to 4 carbon atoms, alkoxycarbonyl (where alkoxy is of 1 to 4 carbon atoms), phenoxy, benzoylamino, trifluoromethyl or alkylcarbonyl (where alkyl is of 1 to 6 carbon atoms), X is hydrogen or ##STR2## where R is alkyl of 1 to 17 carbon atoms, phenylamino, phenyl, alkoxycarbonyl-alkyl (where alkoxy is of 1 to 8 carbon atoms and alkyl of 2 to 4 carbon atoms), alkoxy of 1 to 10 carbon atoms or alkoxyalkyl of a total of 3 to 12 carbon atoms, A is chlorine, bromine, alkyl of 1 to 4 carbon atoms or alkoxy of 1 to 4 carbon atoms, B is hydrogen or nitro and n is 0, 1, 2 or 3. On cellulose and cellulose-containing textiles, the dyes, used in the presence of swelling agents, give bluish violet to greenish blue dyeings having very good fastness properties.
