Abstract

Vat dyes containing at least one sulphonic acid group and at least one acylamino group derived from an aromatic or heterocyclic acid are prepared by processes wherein (a) a dianthrimide carbazole of formula <FORM:0982430/C4-C5/1> in which at least one X is an acylamino group as defined above and the other X's are hydrogen or halogen atoms, is treated with a sulphonating agent until at least one sulphonic acid group is introduced, or (b) a corresponding dianthrimide carbazole containing at least one sulphonic acid halide group is subjected to hydrolysis under mild conditions, or (c) a dianthrimide of formula <FORM:0982430/C4-C5/2> wherein at least one X is an acylamino group as defined above which may contain a sulphonic acid group and the other X's are hydrogen or halogen atoms, is carbazolized with simultaneous or subsequent sulphonation if desired, or (d) a dianthrimide carbazole of formula <FORM:0982430/C4-C5/3> wherein at least one X is an acylatable amino group and the other X's for hydrogen or halogen atoms is acylated with a halide or anhydride of an aromatic or heterocyclic acid containing in addition to the acylating group a sulphonic acid group or a sulphohalide group which is converted to a free sulphonic acid group under the reaction conditions, or (e) an aroylaminodianthrimide carbazole of the formula shown above, in which at least one acylamino group carries an HS- grouping, is oxidized until the HS- group is converted into an HO3S- grouping. The invention also comprises the dyes of formula <FORM:0982430/C4-C5/4> wherein at least X is an acylamino group as defined above, the other X's are hydrogen or halogen atoms and at least one acylamino group contains a sulphonic acid group. The dyes give yellow, orange and brown vat dyeings on cellulose fibres. Examples describe the preparation of the dyes.
