Abstract

1,190,835. Disperse monoazo dyes. SANDOZ Ltd. 10 Oct., 1967 [10 Nov., 1966; 29 Nov., 1966], No. 46217/67. Heading C4P. The invention comprises disperse monoazo dyes of general formula wherein R 1 , R 2 and R 6 are C 1 -C 4 alkyl groups; R 3 and R 4 are Cl or Br; and R 5 and R 7 are H or methyl. They are prepared by diazotization and coupling, in acid medium, e.g. at pH 4. The dyes may be used to dye, pad or print linear aromatic polyester fibres, cellulose acetate or triacetate and polyamides in orange and scarlet shades and they reserve wool and cotton.
