Use	acid yellow A- 4R is mainly used for dyeing nylon, resulting in brilliant orange color and excellent fastness. When used for blended fabric, the other fibers are not stained, but the wool is stained seriously.
production method	with 2-nitro-4 '-amino diphenylamine -4-sulfonic acid and m-cresol as raw materials, the former is first diazotized and then coupled with the latter to obtain a product. After salting out, filtration, drying to obtain the finished product..
