Abstract

Aminoanthraquinones are condensed with sulphochlorides of o-oxycarboxylic acids, other than salicylic acid; in an example, 1 : 4-diaminoanthraquinone is condensed with the sulphochloride of o-cresotinic acid; the product dyes wool bluish-red shades or may be used for dyeing acetate silk or in calico-printing.ALSO:Acetate silk is dyed by means of dyestuffs prepared by condensing aminoanthraquinones with sulphochlorides of o-oxycarboxylic acids, other than salicylic acid; the product from 1 : 4-diaminoanthraquinone and the sulphochloride of o-cresotinic acid gives bluish-red shades.
