Abstract

1411740 Disperse monoazo dyes IMPERIAL CHEMICAL INDUSTRIES Ltd 13 April 1973 [17 May 1972] 7786/75 Divided out of 1398741 Addition to 1256093 Heading C4P New disperse monoazo dyes, free from SO 3 H and COOH groups, of formula wherein R<SP>4</SP> is H, alkyl, cycloalkyl, aryl or aralkyl, R<SP>5</SP> is H or alkyl and Z<SP>2</SP> is a C 7 -C 12 alkyl radical are prepared by azo coupling using diazotized sulphonamidoanilines and appropriate hydroxy-pyridone coupling components. The dyes give greenish-yellow shades on polyester fibres.
