A type of triazinyl aminostilbene fluorescent brighteners (FBs) contains ultraviolet absorption groups has been synthesized by three-step nucleophilic substitution reaction, then use FBs, styrene, Dimethyldiallyl ammonium chloride (DMDAAC) or methyl acryloyloxyethyl trimethyl ammonium chloride (DMC) as polymerization units and ammonium persulfate - sodium bisulfite as initiator to graft copolymerization with gelatinized starch to prepared two kinds of starch graft copolymerization amphoteric fluorescent emulsions (ST-DMDAAC-FBs / ST-DMC-FBs). The structure and properties of products were characterized by 1H-NMR, FT-IR, UV-vis and fluorescence spectra. The physical properties of papers before and after coating by fluorescent emulsion were tested by tensile strength, contact angle, ultraviolet aging test and SEM. The results showed that the tensile strength of ST-DMDAAC-FBS and ST-DMC-FBS increased by 43.1% and 39.7% respectively, the whiteness increased by 15.52% and 15.28% ISO, and the yellow return value decreased by 1.88 and 1.75. The results showed that ST-DMDAAC-FBS and ST-DMC-FBS could both improve papers strength and anti-yellowing, but ST-DMDAAC-FBS had better effect on paper.
