    Abstract: The invention comprises the dyes having the formula wherein F represents an azo or anthraquinone dye radical free from sulphonic acid groups and R represents an alkylene or arylene group. The dyes may contain as substituents in F, OH, halogen, NO2, alkyl, aryl, alkoxy, aryloxy and acylamino groups. They may be obtained by reacting one mole of an acid halide of the formula wherein Hal represents Cl or Br with at least twice the molar amount of an azo or anthraquinone dye containing a primary amino group but no SO3H groups. The anthraquinone dyes used as starting materials may be derived from anthraquinone or condensed anthraquinone derivatives such as benzanthrone, dibenzanthrone, isodibenzanthrone, pyrazolanthrone, anthrapyrimidine, anthraquinacridone, pyranthrone, indanthrone, flavanthrone and perylene tetracarboxylic-imide compounds. Examples are given for the production of dyes in which F is an anthraquinone dye or a condensed anthraquinone dye. They may be used in pastes, flush pastes, printing inks, distempers, binder colours and lakes, or incorporated in synthetic or natural macromolecular substances, or for mass coloration of fibres of acetyl cellulose, polyacrylonitrile, polyesters, polyurethanes and polyvinyl chloride, or of paper, or for colouring inorganic materials, e.g. cement.
