Abstract

The invention comprises monoazo dyes of formula:-<FORM:0906291/IV (b)/1> wherein R is methyl or ethyl. They give violet shades when used to colour lacquers or to dye or print textile materials. In an example 1-amino-4-benzoylamino-3-methyl-6-methoxybenzene is diazotised and coupled with 1-(21:31- hydroxynaphthoylamino)-4-ethoxy- or -methoxybenzene. Specification 303,838 is referred to.
