Abstract
The invention comprises dyes obtainable by carbazolizing and halogenating, in either order, anthrimides of the formula <FORM:0728554/IV (c)/1> wherein one or several Y's mean arylamino groups. In examples, (1) the anthrimide from a ,a 1-dichloracedianthrone and 1-aminoanthraquinone is carbazolized in an aluminium chloride-sodium bisulphite-sulphur dioxide melt (example 3 of Specification 410,552) and either bromine or chlorine is added to the melt together with a little iodine, or the carbazole is separated and heated with sulphuryl chloride in o-chlortoluene; alternatively, the anthrimide may be heated with sulphuryl chloride in o-chlortoluene, followed by carbazolization. Also in examples, (2) the anthrimide from a ,a 1-dichloracedianthrone and 1-amino-5-benzoylamino-anthraquinone is carbazolized in chlorsulphonic acid (example 4 of Specification 410,552), and the product is brominated without separation; (3) the reaction product from tetrachloracedianthrone and 4 mols. 1-aminoanthraquinone (example 3 of Specification 690,006) is carbazolized in an aluminium chloride-sodium chloride-sulphur dioxide melt, followed by bromination without separation. The arylamino groups Y may contain as aryl groups residues of the benzene, naphthalene, dibenzpyrenequinone, or acedianthrone series. Specification 453,853 also is referred to.
