Water-soluble anthraquinone dyes

Abstract

There are described new violet water-soluble anthraquinone dyes corresponding to the formula ##STR1## wherein R.sub.1 represents a straight-chain or branched-chain alkyl group having 4 to 8 carbon atoms, R.sub.2 and R.sub.3 independently of one another represent a straight-chain or branched-chain alkyl group having 1 to 4 carbon atoms, R.sub.4 represents hydrogen, an optionally acylated amino group, or a fibre-reactive radical bonded by way of an amino group, R.sub.5 represents hydrogen or a straight-chain or branched-chain alkyl group having 1 to 4 carbon atoms, and the phenyl rings A and/or B can be further substituted, with the proviso that one X of the symbols X.sub.1 and X.sub.2 represents the --SO.sub.3 H -- group, and the other X represents hydrogen; and also a process for producing these dyes by means of a phenol melt; and the use of the new water-soluble anthraquinone dyes for dyeing and printing textile materials, particularly natural and synthetic polyamide materials.
