| titleOfInvention | Monoazo dyes |
| abstract | The invention comprises dyes of formula <FORM:1035916/C4-C5/1> wherein R1 is an acyl radical or a triazinyl radical having a size enabling the compound to dissolve in substantially neutral aqueous solution and capable of imparting solubility characteristics which will permit neutral dyeing of polyamide fibres, wherein R2 is a meta- or para-phenylene radical which may contain C1 or C2 alkyl or alkoxy substituents, R1 and R2 being devoid of water-solubilizing groups such as -SO3H, -COOH or -SO2NH2. The dyes are prepared by coupling a diazotized m- or p-nitroaniline with 2-amino-8-naphthol-6-sulphonic acid, reducing the nitro group and acylating the resultant aminoazo dye. Specified acylating agents in examples are benzoyl chloride, butyl or ethyl or isopropyl or isoamyl or n-hexyl chloroformate, butyryl or 2-chloropropionyl or hexanoyl or octanoyl or lauroyl chloride, 2 - chloro - or 2,4 - dichloro - benzoyl chloride, m- or p-nitrobenzoyl chloride, cinnamoyl chloride, phenylacetyl chloride, phenoxyacetyl chloride, phenyl or 1-naphthyl isocyanate, furoyl chloride and cyanuric chloride. The product resulting from th cyanuric chloride condensation is further reacted with ammonia to replace the labile chlorine atoms by -NH2 groups. The dyes give red shades on natural and synthetic polyamide fibres from neutral baths. |
