Description
Известно, что можно получить выдающиес по прочности окраски волокнистых материалов и других носителей , примен нерастворимые азокрасители . Обычно дл их получени окрашиЕ аемый материал обрабатывают растзором азосоставл ющей компсненты и затем раствором диазосоединени .It is known that it is possible to obtain outstanding color fastness of fibrous materials and other carriers using insoluble azo dyes. Usually, to obtain them, the stained material is treated with a strain of the azo-component component and then the diazo compound solution.
