Abstract

The invention comprises water-soluble organic dyestuffs characterized by containing at least one grouping of the general formula <FORM:0952123/C3/1> wherein one Y is a fluorine atom or a nitro group, the other Y is a hydrogen atom and A is a nitrile or -SO2R group, R being an aliphatic, araliphatic, aromatic, cycloaliphatic or heterocyclic residue. The dyes are prepared by reacting amino groups of water-soluble dyestuffs with functional derivatives of aromatic carboxylic acids of the general formula <FORM:0952123/C3/2> or they are prepared in known manner from intermediates containing at least one grouping of the first general formula above. The dyes contain at least one water-solubilizing group, e.g. the sulphonic acid group. The dyes may be of the azo, anthraquinone, azine, oxazine, thiazine, nitroso, nitro, azomethine, phthalocyanine, acridine, quinoline, triarylmethane, perinone or indigoid series. The azo dyes may be mono-, dis- or polyazo dyes and may contain in complex linkage metal atoms such as copper, chromium and cobalt. The dyes may be used for dyeing wool, silk, polyamide fibres or leather and react with material containing hydroxyl groups, e.g. cotton or regenerated cellulose whilst heating in the presence of alkaline agents. In examples: 1-amino-3-(41-fluoro-31-methyl-sulphonbenzoylamino) - benzene - 6 - sulphonic acid is diazotized and coupled with the sodium salt of 1-(41-sulphophenyl)-3-methylpyrazolone to form a yellow dye; representative of many alternative coupling components specified are 1 - methylpyrazolone - 3 - carboxylic acid, 2-naphthol - 6, 8 - disulphonic acid and 2-(31-sulphophenylamino) - 8 - naphthol - 6 - sulphonic acid, and of alternative diazo components specified are 1-amino-3-(61-nitro-31-methyl-sulphon - benzoylamino) - benzene - 6 - sulphonic acid and 1-amino-3-(41-fluoro-31-cyano-benzoylamino) - benzene - 6 - sulphonic acid (1); 1 - amino - 3 - (41 - fluoro - 31 - methyl-sulpho - benzoylamino) - benzene - 6 - sulphonic acid is diazotized and coupled with 2-amino-8-naphthol-3, 6-disulphonic acid (2); 1-amino - 3 - (41 - fluoro - 31 - methyl-sulphon - 11 - benzoyl)-aminobenzene-6-sulphonic acid is diazotized and coupled with 1,3-diamino-benzene-4-sulphonic acid and the product is coupled with diazotized 1 - amino - 3 - (41 - fluoro 31 - methyl-sulphonbenzoyl) - aminobenzene - 6 - sulphonic acid (3); copper phthalocyanine is converted to a sulphochloride and reacted with 4,41-diamino-diphenyl-2, 21-disulphonic acid and the product is reacted with 4-fluoro-3-methylsulphon-1-benzoyl chloride. Additional alternative starting materials are listed.
