Abstract

1465941 Monoazo dyes derived from 2-amino- 3 - carboxy - 5 - nitro - thiophene IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Jan 1975 [6 Feb 1974] 05387/74 Addition to 1425029 Heading C4P Novel dyestuffs of the formula (wherein Z is H or C 1-4 alkyl or alkoxy; Y is H, Cl, Br, C 1-4 alkyl or alkoxy or acylamino; A<SP>1</SP> and A<SP>2</SP> are each C 2-6 alkylene; and R<SP>1</SP> and R<SP>2</SP> are each alkyl or phenyl but are not both methyl) are prepared by coupling diazotized 2-amino-3- carboxy - 5 - nitro - thiophene with appropriately substituted anilines. They dye aromatic polyester textile materials in blue, reddishblue and greenish-blue shades.
