Abstract
An antistatic article comprises a thermoplastics polymeric substrate having at least one surface layer comprising (a) a polychlohydrin ether of an ethoxylated hydroxyamine and (b) a polyglycol diamine, the total alkali metal content of components (a) and (b) not exceeding 0.5% of the combined weight of (a) and (b). Articles such as fibres, filaments, sheets and films, particularly polyester films, are thereby rendered antistatic without detriment to the optical characteristics thereof.
