Abstract

Chromium complexes of monoazo dyes of formula <FORM:0994927/C4-C5/1> wherein R is an o-phenylene radical and R1 is a radical of the benzene series and R and R1 may contain further non-acid-dissociating substituents which are not linked to R and R1 via a nitrogen atom are prepared by reacting a monoazo dye of the above formula with sodium bichromate and glucose in formamide preferably at an elevated temperature. The dyes of the above formula may be prepared by the coupling process from diazotized anthranilic acids and appropriate acetoacetanilides. The chromium complexes give yellow shades on wool, silk and synthetic polyamide and polyurethane fibres. Examples describe the preparation of the monoazo dyes and the chromium complexes.
