Abstract

Azo dyestuffs for hydrophobic fibres These dyestuffs have the general formula: (in which A is the residue of a coupling agent, R1 independently represent a hydrocarbon group, which may be substd. or contain hetero atoms; the nucleus B can also be subst). They can be produced by sulphonating the nucleus of the corresp. azo compound. The products are characterized by excellent fastness to thermal fixing, sublimation, pleating, fumes, dry and wet cleaning, perspiration, light, heat (to 220 degrees) etc.
