Abstract

The invention comprises basic dyes of formula <FORM:1016371/C4-C5/1> wherein R1 is hydrogen or a C1-C8 alkyl group, R2 is a methyl or ethyl group, R3 is a chlorine or bromine atom, cyano or C1-C8 alkyl-sulphonyl group, R4 is a hydrogen, chlorine or bromine atom and Z is a C1-C3 alkylene group or the group -CHOH.CH2-. The dyes are prepared by diazotizing an amine of formula <FORM:1016371/C4-C5/2> and coupling the diazonium compound with a compound of formula <FORM:1016371/C4-C5/3> The dyes are preferably used to colour articles made from polymers composed of more than 80% acrylonitrile in red, blue or brown shades.
