    Abstract: 1. A vat dye based on a condensed reaction product of monobromofluoranthene which contains not more than 7% of dibromofluoranthene with 1-amino-4-benzoylaminoanthraquinone, obtainable by carrying out the condensation of the reaction product to give the carbazole compound at from 50 to 70 degrees C in 83-88% strength sulfuric acid and, after the conversion to the carbazole compound, effecting further bromination to a bromine content of from 20 to 23% by weight.

    Abstract: The medium contains a carrier layer onto which a light-absorbing layer is applied which either consists of a dye of the formula or which contains this dye. In the formula, at least one X is and the other X are hydrogen, -OR , -SR and/or -NO2, A is alkyl which may be substituted, phenyl, benzyl or phenylethyl, or a group in 2, 3, position, n is 0, 1, 2, 3 or 4, the number of -NO2 groups being 2, R , R and R are hydrogen, alkyl, alkoxyalkyl, cyclohexyl, phenyl or phenylalkyl, the phenyl radicals possibly being further substituted, or are a saturated 5- or 6-membered heterocyclic ring and R is alkyl, alkoxyalkyl or C2/C3-alkylcarboalkoxy. The dyes have an absorption maximum in the range from 600 to 660 nm. The recording medium can be written and read with He-Ne lasers.

    Abstract: The invention relates to dye mixtures containing 5 to 95 % by weight of a dye of the formula (I), in which R is C1-C4-alkyl, and 5 to 95 % by weight of one or a plurality of dyes of the formulas (II), in which R has the above meaning, (III) and/or (IV). The invention also relates to dye preparations containing the novel dye mixtures, and the use of the novel dye mixtures for the dyeing or printing of cellulose acetate in the form of textiles.

    Abstract: Process for the preparation of anthrimides in a one-pot reaction in which a) leuco-1,4-diaminoanthraquinone is oxidised in nitrobenzene to give 1,4-diaminoanthraquinone, b) the diamine obtained is monobenzoylated at 33 to 39 DEG C in the presence of 0.8 to 1.2 % by weight of water and acid-binding agents and c) the 1-amino-4-benzoylamino compound obtained is condensed with an aromatic halogen compound in the presence of copper to give the anthrimide. During the benzoylation, an aminobenzoylaminoanthraquinone is obtained which contains less than 3 % by weight of starting material and of the bis-benzoylamino compound. In the carbazolisation, the anthrimides obtained by the process yield vat dyes which have the same properties as the dyes of the prior art. h

    Abstract: The invention relates to dye mixtures containing 20 to 90 % by weight of the dye of formula (I), and 10 to 80 % by weight of one or a plurality of dyes of formulas (II), (III) and/or (IV), R being hydrogen, 2-hydroxyethyl or 2-cyanoethyl. The invention also relates to dye preparations containing the novel dye mixtures, and the use of the novel dye mixtures for the dyeing or printing of cellulose acetate in the form of textiles.
