Abstract

325,204. Soc. of Chemical Industry in Basle. Sept. 10, 1027, [Convention date]. Divided on 297,003. Azo dyes, soluble metal compounds of.-Monoazo dyes containing metals are obtained by treating monoazo dyes derived from 2: 5: 7-aminonaphtholsulphonic acid or an N-substituted derivative thereof as coupling component with an agent yielding more than one metal or with agents in succession yielding different metals. The use of agents yielding magnesium is excepted. The products are suitable for dyeing textiles, such as cotton, and for colouring varnishes. The following examples are specified. (1) The dyestuff 5- nitro-2-aminophenol # phenyl (or 4<1>-tolyl)-2 : 5 : 7-acid is boiled with a solution containing copper sulphate and nickel sulphate, a solution of chromium fluoride is then added and the boiling continued; the product dyes cotton pure blue from a neutral or alkaline Glauber's salt bath. (2) Similar products are obtained by omitting the nickel sulphate and using varying proportions of copper and chromium. An example is also given of the dyeing process as applied to cotton. Specification 16803/15 is referred to.
