Abstract

Cupriferous dyestuffs are made by treating with a compound of divalent copper the azo dyes obtained by coupling a m-aminooxy- or m-dioxy-compound of the benzene series (1 mol.) with a diazotized aminodiphenylamine sulphonic acid (1 mol.) and with 2 mols. of the same or another diazo or diazoazo compound containing no groups capable of leading to the formation of complex metal compounds. They dye leather in brown shades. In examples the following dyes are treated with ammoniacal copper sulphate: (1)--(2) 4<1>-nitro-4-aminodiphenylamine-2<1>-sulphonic acid \sz m-aminophenol or resorcinol; (3) 4-nitroaniline-2-sulphonic acid \sQ m - aminophenol \sM 4<1>-nitro - 4 - aminodiphenylamine - 2<1> - sulphonic acid; (4) aniline --> resorcinol \sx 4<1>-nitro-4-amino diphenylamine-2<1>-sulphonic acid; (5) aniline sulphanilic acid \sQ resorcinol \sM 4<1>-nitro-4-aminodiphenylamine-2-sulphonic acid. The Specification as open to inspection under Sect. 91 comprises the use of 2 mols. of any diazo or diazoazo compound for the second coupling. This subject-matter does not appear in the Specification as accepted.
