Abstract

1465391 Monoazo dyes derived from 2-amino- 3 - carboxy - 5 - nitro - thiophene IMPERIAL CHEMICAL INDUSTRIES Ltd 8 Jan 1975 [6 Feb 1974] 05388/74 Addition to 1425029 Heading C4P Novel dyestuffs of the formula wherein T is H, Cl, Br, C 1-4 alkyl or alkoxy or acylamino; Z is H or C 1-4 alkyl or alkoxy; X is alkyl, hydroxyalkyl, cyanoalkyl, aralkyl, aryl cycloalkyl, -A<SP>1</SP>-CO.OR<SP>1</SP>, -A<SP>1</SP>-OR<SP>1</SP>, or -A<SP>1</SP>-O.CO.OR<SP>2</SP>; and Y is alkyl, cyanoalkyl, hydroxyalkyl, -A<SP>2</SP>-OR<SP>3</SP>, -A<SP>2</SP>-CO.R<SP>4</SP> -A<SP>2</SP>-O.CO.OR<SP>4</SP>, -A<SP>2</SP>-O.CO.R<SP>4</SP>, or -CH 2 CH(OL)CH 2 Q; in which A<SP>1</SP> and A<SP>2</SP> are each C 1-6 alkylene, R<SP>1</SP> and R<SP>3</SP> are each alkyl, cycloalkyl, aryl, aralkyl, cyanoalkyl or alkoxyalkyl, R<SP>2</SP> and R<SP>4</SP> are each alkyl, cycloalkyl, aryl or aralkyl, L is H or acyl and Q is Cl, Br, OH or -OR<SP>3</SP>, are prepared by coupling diazotized 2-amino-3-carboxy-5-nitrothiophene with appropriately substituted anilines. They are used to dye aromatic polyester textile materials in blue, greenish-blue, blue-green, reddishturquoise, turquoise and reddish-blue shades.
