<p>An antistatic polyester film comprising a polyester film and, provided on at least one side thereof, an antistatic layer formed of an antistatic agent (A) composed mainly of a polymer having repeating units having a structure represented by general formula (I) wherein R<1> and R<2> each represent H or CH3; R<3> represents an alkylene group having two to ten carbon atoms; R<4> and R<5> each represent a saturated hydrocarbon radical having one to five carbon atoms; R<6> represents an alkylene group having two to five carbon atoms; n is a number of 0 to 40; m is a number of 1 to 40; and Y<-> represents a halide ion, a mono-or polyhalogenated alkyl ion, a nitrate ion, a sulfate ion, and alkylsulfate ion, a sulfonate ion, or an alkylsulfonate ion. This film is excellent in antistatic property, prevention of back transfer, recovery, abrasion resistance, and blocking resistance, and hence is suitable for use in a magnetic card application where a magnetic layer and an ultraviolet curable ink layer are laminated on the surface of the antistatic polyester film. <CHEM></p> |
