N‐ alkylated derivatives of 4‐anilino‐8‐amino‐1,5‐dihydroxy‐anthraquinone and of 4‐anilino‐5‐amino‐1,8‐dihydroxy‐anthraquinone are obtained either by reaction of the corresponding nitro derivatives with alk ylamines or of the corresponding amino derivatives with alkyl halides. They are excellent dyes for polyester fibre, giving deep greenish‐blue dyeings of good fastness to light and sublimation .
