Research on Ink and Synthesis of 6-Chloro-2-[5-chloro -2-(4-biphenyl-sulfonamido)]phenyl-4-benzoxazinone

Chloro 2 aminobenzoic acid was prepared from 2 aminobenzoic acid by chlorination(hydrochloric acid hydrogen peroxide) in 40% yield.The fluorescent agent with maximum emission wavelength of 550 nm was synthesized by adding 4 biphenylsulfonyl chloride to 5 chloro 2 aminobenzoic acid in pyridine.The volume of pyridine was only 1/4 that reported in the reference 3 while the yield was increased by 20%.Two types of offset printing ink were made(viscosity 5.32 Pa·s,stickiness 4.62,fineness 10 μm and viscosity 31.77 Pa·s,stickiness 10.30,fineness 10 μm),suitable for preventing falsification of the valid credentials.
