Abstract

The invention comprises a dye of the formula:-<FORM:0777789/IV(b)/1> and a method of making it by condensing fluorenone - 2 - carboxylic acid or a functional derivative thereof with 1 - amino - 5 - benzoylamino - anthraquinone. The product dyes or prints vegetable fibres golden-yellow shades. Examples describe the reaction of fluorenone - 2 - carboxylic acid chloride with 1 - amino - 5 - benzoylamino - anthraquinone in o - dichlorobenzene.
