Abstract
The invention comprises metal complexes that contain one chromium atom complexed with two molecules of different monoazo dyes, one being of formula <FORM:1001717/C4-C5/1> wherein R, Y and Z are a hydrogen or chlorine atom or a nitro group, but at most R and Y are simultaneously a nitro group and R may also be a C1-C5 alkyl or alkoxy group, and X is a hydrogen or chlorine atom, and the other being of formula <FORM:1001717/C4-C5/2> wherein one X is a sulphonic acid group and the others are hydrogen atoms, Y is a hydrogen atom or a nitro group and Z is a hydrogen or chlorine atom or a nitro or C1-C5 alkyl or alkoxy group and in which Y and Z must be different from each other. The complexes are prepared by reacting a 1 : 1-chromium complex of the second dye specified above with an equimolar proportion of the first dye. The complexes are used to dye natural and synthetic nitrogenous materials in blue or grey shades. The preparation of the complexes is described in an example and further complexes are specified in a table. Specification 765,355 is referred to.
