Antistatic polyester film and antistatic coating liquid

Abstract

An antistatic polyester film and an antistatic coating liquid are provided. The antistatic polyester film includes a polyester substrate and an antistatic coating layer formed on the antistatic polyester film. The antistatic coating layer is formed by applying an antistatic coating liquid on the side surface of the polyester substrate by an in-line coating, and drying the antistatic coating liquid. The antistatic coating liquid includes an aqueous solvent, a conductive additive, and a water soluble polyester resin. Based on a total weight of the antistatic coating liquid being 100 wt %, the aqueous solvent ranges between 50 wt % and 85 wt %, the conductive additive ranges between 1 wt % and 20 wt %, and the water soluble polyester resin ranges between 2 wt % and 40 wt %.
