Use | acid yellow GR is suitable for dyeing wool, silk, nylon and wool blended fabrics with brilliant yellow. Good levelness and discharge. When it is used for dyeing wool with other fibers in the same bath, the staining of silk is serious, the acetate fiber is slightly stained, and the cellulose fiber is not stained. |
production method | to 2, 5-dichloro-4-aminobenzenesulfonic acid and 1-phenyl-3-methyl-5-aminopyrazole are used as starting materials, the former is first diazotized, and then coupled with the latter to obtain a product. After salting out, filtration, drying, grinding to get the finished product.. |
