Abstract
Abstract Water copper complex disazo dyestuffs of the formula ##STR1## had been found wherein A is phenyl or naphthyl, C is phenylene or phenylene substituted by lower alkyl, C and C' together are naphthylene, B is naphthylene, m is 1, 2, 3, 4, 5 or 6 and Y is --SO 2 --CH═CH 2 or --SO 2 --CH 2 --CH 2 --Z wherein Z is hydroxy, methylsulfonyloxy, p-tolylsulfonyloxy, acetoxy, dimethylamino, diethylamino, thiosulfato, phosphato or sulfato, which are well suitable for dyeing and printing wool, silk and polyamide fibres from an acidic, neutral or slightly alkaline medium, and they are particularly valuable for dyeing and printing cotton and other natural or regenerated cellulose fibres, yielding dyeings and prints distinguished by high tinctorial strengths and intense shades, such as navy blue, grey, black, brown or red brown, having good fastnesses especially to washing, to chlorinated water to light and to dry-cleaning.
