Abstract
The synthesis of a series of acid dues obtained by diazotization of p- alkylanilines and coupling with 1-(and 2-) naphthol sulphonic acid der ivatives is described The effects of the alkyl groups on the colour, d yeing, and fastness properties of the dyes are discussed. The dyes col oured polyamide fibres well. It is concluded that substantivity, water -repellency, and wet-fastness of the dyes an polyamide fibres increase with increase in the chain length of the alkyl groups, provided that the dyes dissolve completely in the dyebath.
