Use | reactive brilliant blue P-3R is used for dyeing cotton and viscose fibers, and printing of fabrics, and the dyeing fastness is excellent, is important for the blue dye. |
production method | with bromamine acid, 2,4, 6-trimethyl-3, 5-diaminobenzenesulfonic acid, M-aminobenzene sulfonic acid and cyanuric chloride as raw materials. The product is obtained by first condensing bromine with 2,4, 6-trimethyl-3, 5-diaminobenzenesulfonic acid, then with cyanuric chloride, and finally with M-aminobenzenesulfonic acid. After salting out, filtration, drying to obtain the finished product.. |
