FIELD: paper-making and textile industry. SUBSTANCE: invention involves manufacture of commercial optical bleaching agents based on fluorescent derivatives of 4,4'-bis-(1,3,5-triazin-2-yl-amino)stilben-2,2'-disulfoacid. Commercial optical bleaching agent comprises, wt.-%: florescent derivatives of 4,4'-bis(1,3,5-triazin-2-yl-amino)- -stilben-2,2'-sulfoacid, 100; dye, 0.05-0.25. Bleaching power is increased by 1.5-2 times and expnsive optical bleaching agent is saved. EFFECT: improved bleaching power.
