Abstract
An N-substituted-1-aminoanthraquinone-2-sulphonic acid carrying as N-substituent one or two alkyl, aryl and/or aralkyl groups is halogenated by known general methods and the halogen atoms so introduced replaced by an unsulphonated primary or secondary amino group. The starting materials may be obtained by the process of Specification 399,528. In an example 4 - bromo - 1 - methylaminoanthra - quinone - 2 - sulphonic acid (prepared by brominating 1 - methylaminoanthraquinone - 2 - sulphonic acid) is condensed with p-toluidine; it dyes wool blue shades. Specification 27187/07, [Class 2], also is referred to.
