| abstract | Azo dyes are made on the fibre by coupling a diazo compound of the benzene series devoid of azo, sulpho, nitro, cyano or carboxy groups with 4 : 4<1> - bisacetoacetyldiaminostilbene or 2 : 2<1> - dichloro - 4 : 4<1> - bisacetoacetyldiaminostilbene. The coupling components have a high substantivity for cotton and the dyeings are exceptionally fast to kier-boiling. In examples the following diazo components are specified: 4-, 5-, and 6 - chloro - o - toluidine, o - and m - chloraniline, 4 - chloro - o - anisidine, 2 : 5 - dichloraniline. Specifications 210,217 and 211,772, [both in Class 2 (iii), Dyes &c.], are referred to. 4 : 4<1> - Bisacetoacetyldiaminostilbene and 2 : 2<1> - dichloro - 4 : 4<1> - bisacetoacetyldiaminostilbene are made by heating the respective diamine with two molecular parts of an acetoacetic ester in the presence of a solvent or diluent, e.g. chlorobenzene and advantageously in presence of a tertiary organic base e.g. pyridine. |
