A series of antistatic quaternary ammonium salts with single or multiple UV-curable functional group were synthesized by DMAEMA .The UV-curable antistatic coating was obtained by combining UV-curable coatings technology with antistatic technology. Curing time, washability and thermal stability of the UV-curable films were studied.The influences of kinds and concentration of the antistatic agent on the antistatic properties were discussed.The results showed that the surface resistivity of coating film decreased to 107Ω and hardly changed after washed 10 times, and the UV-curable coating could be cured quickly to give a film with excellent antistatic properties and washability .The results of the TG test showed that the antistatic UV curing coating has good thermal stability.
