Abstract
1,272,431. Dyestuffs. CIBA-GEIGY A.G. 28 April, 1969 [29 April, 1968], No. 21439/69. Heading C4P. The invention comprises water-insoluble dyestuffs free from acid water solubilizing groups which contain at least one α,#-dibromopropionyl amino residue linked to an alkyl group having at least 2 carbon atoms or to an aromatic nucleus, the dyestuffs being free from a metal capable of forming a metal complex and acyl groups which when situated at an alkyl group contain more oxygen atoms than carbon atoms. The dyestuffs may be of the monoazo, disazo, anthraquinone, perinone, nitro or styryl series. They are prepared by (a) acylating a dyestuff containing an amino group with a halide or anhydride of α,#-dibromopropionic acid or (b) diazotization and coupling, at least one of the components containing an α,#-dibromopriopionylamino group substituted at an alkyl group having at least 2 carbon atoms or on an aromatic nucleus. Orange, violet, blue, red, yellow, scarlet, and green shades are obtained in natural, e.g. wool and synthetic, e.g. nylon and polyester, textile materials.
