Abstract
The invention comprises vay dyes which contain a chromophore of formula <FORM:0987965/C4-C5/1> and a sulphoacylamino group attached through its amino nitrogen atom. The dyes are prepared by (a) treating a vat dye containing the said chromophore and an acylamino group with a sulphonating agent until at least one sulphonic acid group has been introduced or (b) acylating a vat dye containing at least one acylatable amino group and a chromophore of the above formula with an acylating agent which contains in addition to the acylating group a sulphonic acid group or a sulphohalide group which is hydrolysed to a sulphonic acid group under the reaction conditions. The sulphonation process (a) may be carried out with oleum or sulphuric acid or with chlorosulphonic acid followed by hydrolysis of the sulphonyl chloride obtained. Specified acylating agents for process (b) are sulphobenzoyl chlorides, benzoic acid sulphochlorides, disulphobenzoyl chlorides, sulphofuran- or sulphothiophene-carboxylic acid halides, sulphocinnamoyle chloride, sulphonaphthoyl chlorides and 2-sulphobenzoic acid anhydride. The dyes give olive-green shades on cotton by the usual vat-dyeing processes. Examples describe the preparation of the dyes.
