Abstract

Azo dyes suitable for dyeing cellulose esters are made by coupling diazotized 6-bromo- or 6-chloro-2 : 4-dinitro-1-aniline with an amine of the general formula <FORM:0449089/IV/1> wherein R = H or an oxyethyl group, and R1=a b -g -dioxypropyl radical in which the OH-group in g -position may be etherified, or in which ring closure has taken place with the elimination of water according to the scheme <FORM:0449089/IV/2> They give pure blue or greenish blue shades. In examples, dyes from the following coupling components are specified: b : g -dioxypropyl-1-naphthylamine, g -methoxy-b -oxypropylnaphthylamine, 1 : 2 : 3 : 4-tetrahydro-3-oxy-a -naphthoquinoline, and 1-oxyethyl-3-oxy-1 : 2 : 3 : 4-tetrahydro-a -naphthoquinoline. Specification 343,502 is referred to.
