Abstract

Azo dyes are formed on the material by coupling tetrazotized 5 : 5<1>-diaminothioindigo with a diacylacetyldiamine (e.g. those described in Specifications 211,772 [Class 15 (ii), Dyeing, Processes &c. for], and 384,317. Clear bright green shades fast to kier-boiling and "chemic" are obtained. In examples, the diacetoacetyl derivatives of o-tolidine and 4 : 4<1>-diaminostilbene are specified as coupling components. Specification 210,217, [Class 15 (ii), Dyeing, Processes &c. for], also is referred to.
