Abstract
The invention comprises formazane dyes and their metal complex compounds which in the metal free form are of formula <FORM:0956455/C3/1> wherein A and B are identical isocyclic aromatic radicals, R is an aryl radical and X1 and X2 are identical groups capable of metal complex formation and occupying positions adjacent to the nitrogen bridge. The dyes are prepared by coupling, in an alkaline medium, 2 moles of a diazo compound of an isocyclic aromatic amine which contains in an adjacent position to the diazo group a metallisable group or a substituent convertible thereto under metallizing conditions, with 1 mole of a methylarylketone and metallizing the dye obtained if desired in substance or on the fibre. The metallization may be carried out by customary methods using copper, nickel, cobalt or zinc compounds. The dyes may be used to colour any natural or synthetic fibre but are preferably used to dye wool, silk and synthetic polyamides. In examples, 2 moles of a diazo compound of the amines specified below are coupled with 1 mole of the ketone also specified and treated with copper, cobalt or nickel yielding agents: 2-aminobenzoic acid, 4 acetylaminoacetophenone; 2 amino phenol 4 sulphonic acid anilide, 1 - acetylnaphthalene; 4 - nitro - 2 - aminophenol, acetophenone; 1 - amino - 2 - naphthol - 4 - sulphonic acid, acetophenol; 1-amino-2-hydroxy-3 - carboethoxyamino - benzene - 5 - sulphonic acid, sodium salt of 3-phenyl-3-oxo-propionic acid. Acylamino groups in the dyes so produced may be saponified and condensed with polyhalo-triazines or -pyrimidines. Many alternative reactants are specified. Specifications 822,047 and 822,948 are referred to.
