Abstract

1,161,006. Formazane azo dyestuffs. J. R. GEIGY A.G. 21 April, 1967 [22 April, 1966], No. 18457/67. Heading C4P. The invention comprises heavy metal-containing formazane azo dyes of the formula wherein each of A and B represents the radica<SP>l</SP> of a diazo component which contains X or X<SP>1</SP> in o-position to the nitrogen bond, each of X and X<SP>1</SP> represents a radical of a metal-binding substitutent, one of D and E represents the radical of a diazo component and the other that of a coupling component, Me represents a heavy metal of atomic numbers 24 to 30, Y represents a fibre reactive group bound to A, B or E optionally by way of a bridging member, which group contains at least one labile substituent or it contains an unsaturated carbon to carbon linkage; Z represents a water solubilizing group, n is a positive whole number of at most 3, p represents a positive whole number of at most 6, and 8 and t represent 1 or 2, the sum of 8 + t being at least 3. They may be obtained by various azo coupling procedures and metallizing the products, the fibre reactive groups may be introduced before or after the formation of formazane azo dye. Examples are given for the production of the dyes. They are useful for dyeing leather, paper, natural or synthetic polypeptide fibre materials and other cellulose materials.
