Abstract

1351375 Monoazo disperse dyes YORKSHIRE CHEMICALS Ltd 8 Sept 1972 [23 Sept 1971] 44378/71 Heading C4P The invention comprises water insoluble dyes having the formula where R<SP>1</SP> is Cl or Br; R<SP>2</SP> is H, Cl, Br, alkyl, alkoxy or acylamino; R<SP>3</SP> is H, alkyl or alkoxy; R<SP>4</SP> is alkylene; R<SP>5</SP> is a direct link, -O- or -NH-; R<SP>6</SP> is an alkyl, aryl, aralkyl, cycloalkyl or heterocyclic radical and R<SP>7</SP> is an alkyl group. The alkyl, aryl, aralkyl, cycloalkyl and heterocyclic radicals present may be substituted but not by SO 3 H or CO 2 H groups. The dyes may be obtained by diazotization and coupling and give red and violet shades on hydrophobic fibres, e.g. polyester, polyamide, polyacrylonitrile and cellulose acetate fibres.
