The invention relates to a thermoplastic composition comprising at least a copolymer of ethylene and an ,-unsaturated C₃-C₈ carboxylic acid, from about 10 to 99.9% neutralized with Lithium, and at least from about 0.01 wt % to about 2 wt % of a migrating antistatic agent. The invention also relates to films, sheet and molded articles comprising the above composition. The composition, film, sheet or molded article of the invention show good antistatic properties and preferably have a surface resistivity equal or less than 10E¹¹. The composition, film, sheet or molded article of the invention can in particular be used as a protective transparent coating or layer on abrasion and scratch-exposed objects.
