Abstract

Water-insoluble azodyestuffs are prepared in substance or on the fibre by coupling diazo compounds of amines of the formula <FORM:0496735/IV/1> in which X is a sulphonamide group, the hydrogen atoms of which may be substituted, and Y and Z, which can be the same or different, are alkyl or halogen, with the b -naphthylamide of b -hydroxynaphthoic acid. The diazo compounds may be employed in the form of diazoamino compounds. The following diazo components are specified: 1.2-dimethyl-, 1.2-dichloro-, and 1 - chloro - 2 - methyl - 4 - sulphodimethylamide-5-aminobenzene. Specification 279,146, [Class 2 (iii)], is referred to.
