Abstract: WATER-INSOLUBLE MONOAZO DYESTUFFS OF THE FORMULA
1-(D-N=N-),2-Y,4-(O2N-C(-CH3)2-CH2-N(-R)-),5-Z-BENZENE
WHEREIN D AS THE REST OF A DIAZO COMPONENT IS NITROPHENYLENE, CHLOROPHENYLENE, NITRO-CYANO-PHENYLENE, NITROCHLORO-PHENYLENE, NITROFLUOROMETHYL-PHENYLENE, DINITRO-TRIFLUORO-METHYL-PHENYLENE - DINITRO-CHLORO-PHENYLENE OR NITRO-DICHLORO-PHENYLENE, Y IS HYDROGEN, LOWER ALKYL, LOWER ALKOXY OR ACETYLAMINO, Z IS HYDROGEN, LOWER ALKYL OR LOWER ALKOXY AND R IS HYDROGEN OR LOWER ALKYL. THE DYESTUFFS ARE DISTINGUISHED BY A GOOD COLOR BUILD-UP AND ARE SUITABLE FOR DYEING AND PRINTING POLYESTER AND POLYESTER-CONTAINING FIBERS FAST TO LIGHT, WASHING AND THERMOFIXATION.-

Abstract: New beta -chloroethylsuflonylmethyl-benzoic acid halides which can serve as fibre-reactive anchors for thesynthesis of novel organic, water-soluble compounds, preferably dyestuffs, having fibre-reactive and fibre-finishing properties, such as preferably dyestuff properties, and containing, as a fibre-reactive group, one or two beta -chloroethylsufonylmethylbenzoic acid amide groups. For the synthesis of these novel fibre-finishing compounds, said new beta -chloroethylsulfonylmethyl-benzoic acid halide compounds are reacted with an organic, water-soluble compound having fibre-finishing properties and continuing one or two amino groups. Also precursors of the fibre-finishing, fibre-reactive compounds, containing said beta -chloroethylsulfonylmethyl-benzxoic acid amid grouping, can be employed for their synthesis. The novel fibre-finishing compounds can be applied onto suitable fibre materials, such as especially cellulose fibre material and natural or synthetic polyamide fibre materials, and fixed on these fibre materials in a manner similar to application and fixation methods usual in the technique for fibre-reactive compounds. The fibre-finished material, such as dyed material, shows very good wet fastnesses.
