The related synthesis technique for environment-protective triazinylamino diphenyl ethylene fluorescer in paper-making, paint and ink comprises: with ANSD acid as initial reactant, composing asymmetric fluorescer; designing a new synthesis path for the composite mixed and quaternary fluorescers; solves the pollution problem basically, and spreads application range. Wherein, the substituents of R1 and R2 are independent amino acid residues with hydrogen atoms on amido removed, such as, the aminobenzenesulfonic residue (I) and o-aminobenzenesulfonic residue (II); the R3 and R4 are independent alkamine residues or aminoalkyl residues with hydrogen atoms on amido removed, such as, morpholinyl(III), phenylamimo(IV), diethanolamimo(-N(CH2CH2OH)2), diacetylamino(-N(C2H5)2), ethanolamimo(-NCH2CH3OH), triethanolamimocation(V), triethylaminocation(VI).
