Abstract

Procedure for the preparation of complex disazo dyes with 1: 1-copper, 1: 2-chromium and 1: 2-cobalt, which in the metal-free form correspond to the general formula (1) **(See formula)** where D represents the radical of a diazo component of the benzene or naphthalene series, which in ortho position with respect to the azo group carries a hydroxy group, n means the numbers 0 or 1 and m means the numbers 1 or 2, and X means a grouping of the formula (2) **(See formula)** or (3) **(See formula)** in which R'signifies a hydrogen atom or an alcoholic group, R''signifies a hydrogen atom or an alcoholic or phenyl group, and Y and Y' signify fluorine or chlorine atoms, characterized in that the dyes are coupled monoazo complexes with 1: 1-copper, 1: 2-chromium or 1: 2-cobalt, which in metal-free form correspond to the general formula (4) **(See formula)** in which D and n have the meanings mentioned above, with a diazotized arylamine of the general formula (5) **(See formula)** in which X and m have the meanings mentioned above.
