Condensation of 2‐bromo‐1,4‐dihydroxyanthraquinone with alcohols and phenols affords the 2‐ether derivatives, which colour synthetic‐polymer fibres, particularly polyester, in yellow‐orange hues of good build‐up and light fastness. The influence of the 2‐ether substituent on the colour of these 1,2,4‐tri‐donor‐substituted anthraquinones is discussed, together with the relative influence of the electron acceptor 2‐sulphone substituent.
