摘要：

The synthesis of a series of acid dyes obtained by diazotization of p-alkylanilines and coupling with perfluorobutamido-1-naphthol sulphonic acid derivatives is described. The effects of alkyl groups and the perfluorobutamido group on the colour, dyeing, water-repellent and fastness properties of the dyes ape discussed. The dyes coloured polyamide fibres well. It is concluded that dyes with the perfluorobutamido group have low er substantivity, on polyamide fibres. It Mas also found that substantivity of the dyes on polyamide fibres decreased with increase in the chain length of the alkyl groups. (C) 1998 Elsevier Science Ltd. All rights reserved.
