Abstract

A thermoplastic resin composition having transparency and antistatic properties, comprising 100 parts by weight of a thermoplastic resin (A) having a refractive index of 1.52 to 1.61 and a haze of 40 or less, and 5 to 40 parts by weight of a polyetherester (B) which has a sulfonate group and a polyalkylene oxide group, and is substantially immiscible with the thermoplastic resin (A), the difference in refractive index between the thermoplastic resin (A) and the polyetherester (B) being 0.04 or less. The thermoplastic resin composition has a haze of 40% or less and a surface resistivity of 1.times.10.sup.10 to 1.times.10.sup.14 ohm/square.
