Abstract

Cellulose fibres or textile materials made therefrom are dyed or printed with an aqueous solution or paste of a water-soluble azo, nitro or anthraquinone dye which contains at least one SO2F group, and the dyeing or printing is fixed by steaming. The dyeing or printing may be carried out at an elevated temperature, and dyeing, printing and fixing may be effected in the presence of a weakly alkaline or acid-binding agent. In an example, 1-aminobenzene-3-sulphofluoride is diazotized and coupled with the sodium salt of 1-(41-sulphophenyl)-5-pyrazolone-3 carboxylic acid, mineral acid being partly neutralized, if necessary, by addition of sodium formate or acetate. A yellow water-soluble dyestuff is obtained. Cotton may be dyed or printed with the concentrated aqueous solution and the dyeing, possibly after intermediate drying, may be steamed in the presence of sodium acetate or other acid-binding agent. During steaming the fibres are acylated with the dye, hydrogen fluoride or fluorides being evolved, and a greenish-yellow dyeing is obtained which is fast to wet-processing, has good light-fastness and may be discharged to a pure white. Printing pastes may be made, using conventional thickeners, binding agents and printing auxiliaries. Other diazo components which may be used include 1-aminobenzene-2,3, or 4-sulphofluoride, 1 - aminobenzene - 3 - sulphofluoride - 5 - or 6 - sulphonic acid, 1 amino - benzene-3,5 - disulphofluoride, 1 - amino - 2 - methylbenzene - 5 - sulphofluoride, 1 - amino - 4-methylbenzene - 3 - sulphofluoride, 1 - amino-2,4 - dimethylbenzene - 5 - or 6 - sulphofluoride, 1 - amino - 4 - chlorobenzene - 2 - sulphofluoride, 1 - amino - 2 - chlorobenzene - 5-sulphofluoride, 1 - amino - 2 - methoxybenzene-5 - sulphofluoride and 1 - amino - 4 - methylbenzene - 3 - sulphofluoride - 6 - sulphonic acid. Other specified coupling components are 1-(41-sulphophenyl) - 3 - methyl - 5 - pyrazolone, 1-(31 - sulphophenyl) - 3 - methyl - 5 - pyrazolone, 1 - (21 - carboxy - 41 - sulphophenyl) - 3 - methyl- 5 - pyrazolone, 1 - (31 - carboxyphenyl) - 5-pyrazolone - 3 - carboxylic acid, 1 - (31 - sulpho-amidophenyl) - 5 - pyrazolone - 3 - carboxylic acid, 1 - (41 - sulphophenyl) - 5 - pyrazolone - 3-carboxyli acid amide, 1-(51,71-disulpho-21-naphthyl) - 3 - methyl - 5 - pyrazolone, 1 - (41-81 - disulpho - 21 - naphthyl) - 3 - methyl - 5-pyrazolone, 1 - (21 - chloro - 51 - sulphophenyl)-3 - methyl - 5 - pyrazolone, 2 - naphthylamine-3,6 - disulphonic acid, 2 - naphthylamine - 5,7-disulphonic acid, 1 - naphthol - 3,6 - disulphonic acid, 1 - naphthol - 3,6,8 - trisulphonic acid, 2-naphthol - 6 - sulphonic acid, 2 - naphthol - 6,8-disulphonic acid, 2 - naphthol - 3,6 - disulphonic acid, 1 - chloro - 8 - naphthol - 3,6 - disulphoric acid, 1 - acetylamino - 8 - naphthol - 4,6 - disulphonic acid and 1 - acetylamino - 8 - naphthol-3,6-disulphonic acid. Specification 460,224 is referred to.
