Abstract
1377422 Azo dyes containing pyrazolone coupling components SANDOZ Ltd 17 Jan 1972 [20 Jan 1971 22 Jan 1971] 2085/72 Heading C4P Novel dyestuffs of the formula (wherein R is an optionally substituted alkyl or cycloalkyl radical, R 1 is an optionally substituted phenylene or naphthylene radical, R 2 is an optionally substituted alkyl or aryl radical, R 3 is H, optionally substituted C 1-6 alkyl or halogen, and ring A may be further substituted), are prepared (1) by conventional diazotization and coupling using an appropriate 2 – amino – 4 – hydrocarbyloxycarbonylaminobenzene-1-sulphonic acid and an appropriate 1-aryl-3-methyl-5-pyrazolone, or (2) by diazotizing an appropriate 2-amino-4-NHB- benzene-1-sulphonic acid (wherein B is H or acetyl), coupling with an appropriate 1-aryl-3- methyl-5-pyrazolone, deacetylating when necessary, and then condensing with an appropriate haloformic acid ester R.O.CO.hal. The dyestuffs are used for dyeing and printing natural and synthetic polyamide and other textile fibres, paper and leather in yellow shades.
