Abstract
1,177,198. Dyeing synthetic polyamides with acid dyes. FARBENFABRIKEN BAYER A.G. 1 Aug., 1968 [7 Aug., 1967], No. 36811/68. Heading D1B. Synthetic polyamides are dyed with acid dyes in presence of a salt of an aromatic acid of formula I: in which Ar is a mono-or polynuclear aromatic radical, n is 0-4, p is 0.4 and q is 0-2 with the proviso that the sum total of n p and q is 3, 4 or 5 and n is 4 if Ar is naphthalene and p and q are o. Preferably Ar is di or trinuclear and alkali metal or ammonium salts are employed, non-ionic emulsifiers may also be present, examples of synthetic polyamides are polycaprolactam, polyhexamethylene-diamine adipate, poly-11-amino-undecanic acid. In Examples (1 and 5) naphthalene-1, 3, 5, 7- tetrasulphonic acid (Na salt) (2) 1-naphthol-3, 6, 8-trisulphonic acid (Na salt) (3) benzoic acid disulphonic acid (NH 4 salt) (4) naphthalene-1, 4, 5, 8-tetracarboxylic acid (Na salt) are used.
