Reaction dyestuff I (A = starting material of diazonium salt; B = coupling member; C = amino compd.; R = H, Me, Et; all of A, B and C are benzene nuclei or naphthalene nuclei such as 1-amino-4-methoxybenzene, 1-amino-4-methoxybenzene-2, 5-disulfonic acid, 1-aminonaphthalene-2-sulfonic acid, 3-aminophenylurea, 1-hydroxy-8-amino naphthalene- 3,6 -disulfonic acid, aniline, 1-aminonaphthalene-6-sulfonic acid) was prepd. by the reaction of azo compd. (IV) with 2,4,6-trifloro-S-triazine at 5-10oC, pH 6-8 followed by reaction of the obtained triazine(V) with amino compd.(VI) at 10-20oC and pH 7-10 to give I.
