A film capacitor element produced from a metallized polyester film is described. In the metallized polyester film, the adhesion between a vapor-deposited metal layer and a polyester substrate is improved by providing a coating layer comprising a specific water soluble or water dispersible resin. The film capacitor produced by the use of the metallized polyester film has good moist heat resistance and long term stability in performance.

Polyester film capacitor element

There is disclosed an electrically conductive polyester film comprising a polyester base film and a coating layer which is formed by applying a coating liquid to said base film, thereafter stretching the coated film and heat-setting the film, wherein said coating liquid is an aqueous composition and contains carbon black in an amount of 30-60% by weight of the solid content and produces a layer when dried at 80.degree. C. for 10 minutes, the rupture elongation of said layer being at least 300% and is heat-settable at 10.degree.-200.degree. C., and said coating layer having a surface resistivity of 10.sup.4 -10.sup.10 .OMEGA./.quadrature. and a surface roughness of not more than 0.05 .mu.m. This polyester film exhibits good electric resistivity and light-shielding proper.

Electrically conductive film

A thermal ink transfer printing material having a specific coating layer on one surface of the base polyester film is described. By providing the specific coating layer, sticking to a thermal head of a printer can be prevented in the thermal ink transfer printing material according to the present invention, and it shows good printing properties.

Thermal ink transfer printing material

Disclosed herein are a stretched antistatic laminate film comprising at least one coating layer containing a polymer having pyrrolidium rings in the main molecular chain, and a polyester film layer, a magnetic recording medium using the same, and a recording material for heat sensitive transfer printing using the same.
