Abstract

Monoazo dyes are prepared in substance or on the fibre by coupling diazotized 5-nitro-2-toluidine with a p-alkyloxyarylide of 2 : 3-oxynaphthoic acid the p-anisidide and p-phenetidide being mentioned; bluish-red, or in light tones, pink shades fast to light are thus obtained on the fibre; the products may also be used in the production of lakes. An example is given of the manufacture in substance of the dyestuff from 5-nitro-2-toluidine and the p-anisidide of 2 : 3 oxynaphthoic acid and of the production of pink and red shades on the fibre by padding with a solution containing the p-anisidide, caustic soda, turkey-red oil, and formaldehyde, and developing with the diazo compound. Specification 6379/12 is referred to.ALSO:Bluish-red or pink shades, fast to light, are produced on the fibre by impregnating with a p-alkyloxyarylide of 2 :3-oxynaphthoic acid and developing with diazotized 5-nitro-2-toluidine. An example is given in which the fibre is padded with a solution containing the p-anisidide or p-phenetidide of 2 :3-oxynaphthoic acid, caustic soda, turkey-red oil and formaldehyde, and developing with the diazo compound. Specification 6379/12, [Class 2 (iii), Dyes &c.], is referred to.
