Abstract

Anthraquinone dyestuffs are made by reacting 1:5-diamino-4:8-dialkoxy- or 1:8-diamino-4:5-dialkoxy-anthraquinone with a chlorinating or brominating agent, such as chlorine, sulphuryl chloride or bromine. Anthraquinones specified are the methoxy-, propoxy-, isopropoxy- and butoxy-compounds and a mixture of the two methoxy-compounds. The halogenation may be conducted in a solvent or diluent and up to about 2 atoms of halogen are introduced. Examples are given. The dyestuffs dye aromatic polyesters such as polyethylene terephthalate blue shades. Specification 815,746 is referred to.
