Abstract

Anthraquinone dyes are made by chlorinating or brominating 1-amino-2-aryloxy-4-hydroxyanthraquinone for example with chlorine, bromine or sulphuryl chloride in a solvent such as sulphuric acid of at least 70% strength, nitrobenzene, o-dichlorobenzene or a concentrated hydrohalic acid. Aryloxy radicals specified are naphthyloxy, tetrahydronaphthyloxy, phenoxy, m- and p-methylphenoxy, m-methoxyphenoxy and p-isopropylphenoxy. The dyes dye aromatic polyesters in red shades from aqueous dispersion.
