Abstract
Diazo compounds, which may or may not contain halogen, are coupled in substance or on the fibre with the 4-chlor- or the 4-brom-3-toluidide of 2 : 3-oxynaphthoic acid (CH3 : NH : Cl=1 : 3 : 4). The shades on the fibre, particularly those derived from halogenated diazo compounds, are very fast to kier-boiling. An example is given of the production in substance of the dyestuff from the 4-chlor-3-toluidide and diazotized 4-chlor-2-anisidine: examples are also given of padding baths containing the toluidides and of pastes for printing thereon containing diazo compounds from 4-chlor-3-toluidine, 4-brom-2-toluidine, 4- or 5-chlor-2-toluidine, 3-nitro-4-toluidine, and 5-nitro-2-aminoanisol. Reference has been directed by the Comptroller to Specifications 6379/12 and 23732/13.ALSO:Diazo compounds are coupled on the fibre with the 4-chlor- or the 4-brom-3-toluidide of 2 : 3-oxynaphthoic acid (CH3 : NH : Cl=1 : 3 : 4); the shades obtained, particularly those derived from halogenated diazo compounds, are very fast to kierboiling.
