Abstract

The invention comprises dyestuffs of formula R1SO2NHSO2R.N=NR3 where R is a benzene residue which may contain substituents other than sulphonic or carboxylic acid groups, R1 is an alkyl or phenyl radicle which may contain substituents except sulphonic or carboxylic acid groups and R3 is the residue of a 1-sulphoaryl-3-methyl-5-pyrazolone or aminopyrazole linked to the azo bridge in the 4-position, the sulphoaryl groups of which may be substituted by halogen atoms or alkyl radicles. The dyestuffs are made by coupling, in weakly acid to alkaline media, diazotized amines of formula R1SO2NHSO2.R.NH2 with appropriate pyrazolones or pyrazoles. Specified diazo components are 1-amino- and 1 - amino - 5 - chloro - benzene - 2 - sulphonic acid (phenylsulphonyl) - amides, 1 - amino - benzene - 2 - sulphonic acid -(41 - chloro-, -methyl- and -acetylamino-, 21 - methyl- and -21,51- and -31,41 - dichloro - phenylsulphonyl)-amides, 1 - amino - benzene - 3 - sulphonic acid -(phenylsulphonyl)-amide and its 21- and 41-methyl and 41-chloro- and -acetylamino derivatives, 1-amino-6-chlorobenzene-3-sulphonic acid -(phenyl-sulphonyl)-amide and its 41-methyl and 31,41-dichloro derivatives, 1-aminobenzene-4 - sulphonic acid -(phenyl - sulphonyl) - amide and its 21- and 41-methyl derivatives. Specified coupling components are 1-(21-, 31- and 41-sulpho-, 21-methyl- and -chloro- and 21,51-dichloro - 41 - sulpho- and 21 - chloro- and 21,31,61 - trichloro - 51 - sulpho - phenyl) - 3 - methyl - 5 - pyrazolones, 1 - (21 - naphthyl - 61 - sulpho and -61,81 - disulpho) - 3 - methyl - 5 - pyrazolones and 1-(31-sulphophenyl) and -(21-naphthyl - 81 - sulpho) - 3 - methyl - 5 - amino-pyrazoles. The dyestuffs dye wool and polyamide and polyurethane fibres from a weakly acid bath in yellow shades. Examples are provided illustrating the preparation of the dyestuffs and their uses in dyeing wool, the components used being selected from those indicated above with the addition of 1-amino-benzene-2-sulphonic acid -(21,51-dimethyl-41-chlorophenyl)-, 1 - amino - 2 - chlorobenzene - 5-sulphonic acid -(21,51-dichlorophenyl) and 1-aminobenzene - 2 - sulphonic acid -(methyl)-sulphonylamides and 1-(21-naphthyl-41,81-disulpho) - 3 - methyl - 5 - pyrazolones and 1 - (21,51-disulphophenyl) - 3 - methyl - 5 - aminopyrazole.
