Abstract

PURPOSE: To obtain excellent antistatic properties, adhesive properties and coated film strength, by coating at least one face of a polyester film on whose surface layer the concentration of sulfonic acid or sulfonate salt is in a specific range, with a layer containing a polymer whose main constituting component is a specific repeating unit, and thereafter drawing it.
CONSTITUTION: It is necessary that the concentration of sulfonic acid or sulfonate salt is 0.002W2.0%. If the concentration is smaller than 0.002%, the coated film strength becomes poor and if the concentration is larger than 2%, the characteristics of base material polyester becomes worse. lt is necessary that 5wt.% or more and 95wt.% or less polymer whose main constituting component is a repeating unit represented by the formula (I) is contained in the coated layer. If the content is less than 5wt.%, the effect improving adhesive properties and antistatic properties becomes insufficient and if the content is more than 95wt.%, the coated film toughness becomes poor. It is especially preferable that balance between the adhesive properties, the coated film toughness and the antistatic properties is good when the content is 10wt.%W30wt.%. The thickness of the coated layer after drawing is usually 0.001W5μm.
