Abstract

This invention discloses an antistatic coating composition and antistatic film coated with the same. The antistatic coating composition comprises a hard coating solution and an antistatic solution. The hard coating solution comprises from 20 to 35 parts by weight of an acrylic oligomer, from 5 to 10 parts by weight of an acrylic monomer, from 40 to 60 parts by weight of a solvent and from 1 to 5 parts by weight of a photoinitiator. The antistatic solution comprises from 0.5 to 5 parts by weight of polyacrylic acid and from 1 to 20 parts by weight of ionic liquid. The antistatic film formed by coating the antistatic coating composition has a pencil hardness of 2H and an initial surface resistivity in the range of 108˜1011Ω/□, and the surface resistivity will maintain in the range of 1010˜1012Ω/□ after isopropanol (IPA) washing.
