Using 2, 4-diaminobenzenesulfonic acid, 1-(4 '-sulfophenyl)-3-formic acid -5-pyrazolone, cyanuric chloride and DSD acid as raw materials, first 2, 4-diaminobenzenesulfonic acid is diazotized, coupled with 1-(4'-sulfophenyl)-3-formic acid -5-pyrazolone, and, the product is obtained by second condensation with DSD acid. The finished product is salted out, filtered and dried.
