Abstract: Yellow to organe azo dyes for natural and synthetic polyamides, e.g. wool, silk, leather, nylon 6 or 6,6; cellulose esters, e.g. -2 1/2 and triacetate and synthetic linear polyesters, have the formula: (where D is a diazo component gp.; X is 2-9 C opt. substd. carbamoyl or carboxylate; M is H, Na, K or opt. substd. NH4 and n is 0 to 3). They are prepd diazotising amines DNH2 and coupling with cpds. (where p is 0 or 1) or by sulphonating cpds. of formula: D-NH-=CX- , esp. with oleum.

Abstract: The dyes are of formula: (in which D is the gp. of a diazo component, M is H, Na, K or opt. substd. ammonium and n is 2, 3 or 4). D is pref. a 2-nitro phenyl gp., opt. substd. in 4-position, and n is 2. They are suitable for dyeing natural and synthetic polyamides, e.g. wool, silk, leather, and esp. nylon-6 and -6, 6.

Abstract: Dyes, of formula (where X is Cl or Br; m = 1-4; n = 1 or 2; and R is H or an opt. substd. (ar)aliphatic or cycloaliphatic gp., pref. (R1O)nR2 or R3OH; where R1 is 2-3C alkylene; n is 1-6; R2 is H, (methyl)phenyl, 1-4C alkyl, acetyl or propionyl; and R3 is 4-10C alkyl) are suitable for dyeing synthetic fibres, esp. polyamides or polyesters, and give better thermofixing fastness than similar un-halogenated monoazo dyes.
