PURPOSE:To obtain an antistatic synthetic resin sheet which does not need post-treatments such as pressing after application of a paint and is excellent in surface smoothness and adhesion of a paint film, by coating at least one of the surfaces of a synthetic resin sheet with an electroconductive ultraviolet- curable paint and irradiating the surface with ultraviolet rays. CONSTITUTION:A synthetic resin paint which can be easily cured by ultraviolet rays and contains an electroconductive substance such as a fine metal powder or an ionic electroconductive resin is used as the electroconductive ultraviolet- curable paint. This paint is mixed with an organic solvent and applied to at least one of the surfaces of a synthetic resin sheet. As the organic solvent, methanol, ethanol, methyl Cellosolve, methyl ethyl ketone or the like is preferable, and it is used preferably at such a mixing ratio that about 7pts. of the solvent is present per 3pts. of the solid matter of said paint. The surface coated with the paint is dried and irradiated with ultraviolet rays. The energy of irradiation is suitably about 0.5-3kW and the time of irradiation is suitably about 10-30sec.
