Abstract

The invention provides water-insoluble monoazo dyes of formula <F\1> in which R1 is a hydrogen or halogen atom or an alkyl, alkoxy or nitro group, R2 is a hydrogen or halogen atom or an alkyl or alkoxy group, R3 is a mononuclear aryl radical and R1, R2 and R3 are free from sulphonic and carboxylic acid groups. The dyes are made by diazotizing amines of formula <FORM:1016089/C4-C5/1> and coupling with 2,3-hydroxynaphthoic acid arylamides, the arylide nucleus of which is mononuclear. In Examples, 1, 4 and wetting agents are used during coupling. The dyes give red-blue colours.
