Abstract

The invention comprises metal complexes that contain a chromium atom bound in complex union with 2 molecules of different monoazo dyes, one of which is of formula <FORM:1001840/C4-C5/1> wherein one of X, Y and Z is a hydrogen atom and each of the others is a hydrogen or halogen atom or a nitro, alkyl or alkoxy group, and the other is of formula <FORM:1001840/C4-C5/2> wherein D is the residue of a diazo compound bound to the azo bridge in a position ortho to the -(CO)n-1-OH group, A is the residue of an azo component linked ortho to an enolized or enolizable keto group or an amino or hydroxy group, n is 1 or 2 and one of the residues D and A contains an SO3H group. The complexes are prepared by reacting an equimolar proportion of one of the specified dyes with a 1 : 1-chromium complex of the other dye. The dyes may be used to colour wool, silk, leather and polyamide and polyurethane fibres in yellow green, glue and brown shades. The preparation of the dyes is described in examples. Specification 765,355 is referred to.
