Abstract

1,189,243. Dyeing with azoic dyes. FARBWERKE HOECHST A.G. 15 May, 1968 [18 May, 1967], No. 23111/68. Heading D1B. Water-insoluble azo dyes are produced on cellulosic or protein fibres by impregnation with a substantive coupling component followed by developing the dyestuff by treating with a diazonium compound of an aromatic amine, and an alkali binding agent in presence of a wetting or dispersing agent preferably at below 35‹C and a pH of 3-8, without removal of any residual coupling component not absorbed in the fibre and without the use of a separate developing bath.
