Abstract
1,171,803. Water-insoluble azo-dyes. FARBWERKE HOECHST A.G. 27 Jan., 1967 [27 Jan., 1966], No. 4245/67. Heading C4P. The invention comprises water-insoluble mono- and dis-azo dyes of the formula wherein D represents a radical of the benzene or azobenzene series which may be substituted on the aromatic nucleus by one or more non- water-solubilizing groups, and A represents a benzene nucleus which may contain one or more further non-water-solubilizing groups. They may be obtained by coupling a diazonium compound of an aromatic primary amine of the formula D-NH 2 with a pyrazolone derivative of the formula in a weakly acid, neutral or weakly alkali medium. Examples are given for the production of the dyes. They are useful for dyeing or printing polyester, cellulose triacetate, cellulose 2¢ acetate, polyamide and polyurethane fibres.
