Abstract

1495673 Reactive naphthyl monoazo pyrazolone dyestuffs HOECHST AG 10 April 1975 [11 April 1974] 14764/75 Heading C4P Novel reactive dyestuffs of the formula wherein X is are prepared by coupling diazotized 1-naphthylamine-4-sulphonic acid with the appropriate pyrazole compound. In the products the X groups may be interconverted by standard procedures. The dyestuffs have use in dyeing fibrous materials containing hydroxy groups or nitrogen, particularly natural or regenerated cellulose (cotton, linen), viscose rayon, silk, wool and synthetic polyamides and polyurethanes. Reference has been directed by the Comptroller to Specifications 1,290,505, 1,268,699 and 1,106,244.
