A metal-deposited polyester film capacitor made of a laminated or wound metal-deposited polyester film which has, on at least one of its surface, a coating layer containing an aromatic polyurethane and a deposited metal layer on the coating layer, which is excellent in moist-heat resistance and has good long-term reliability.

Metal-deposited polyester film capacitor

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

Disclosed herein is a metallized polyester film capacitor comprising: a polyester film; a coating layer formed on at least one side of said polyester film, said coating layer having a thickness (t) of 0.01 to 2 .mu.m and containing 0.1 to 20 wt % of the particles having an average diameter (D) that satisfies the following formula (I); and a metal layer deposited on at least one side of the polyester film having said coating layer.

Metallized polyester film capacitor

A polyester resin film which is biaxially oriented and again oriented in a machine direction and a coating layer formed on at least one surface of the film, in which the coating layer contains at least 50% by weight of a water-soluble or water-dispersible polyester resin having a glass transition temperature of at least 20.degree. C., which film has a good adhesion property.

Polyester film

A capacitor comprising a polyethylene 2,6-naphthalate film as a base film, a coating layer, formed on at least one surface of said base film, which coating layer comprises a water-soluble or water-dispersible resin and has a center line average surface roughness (Ra) of 0.005 to 0.5 .mu.m, and a metal layer deposited on said coated polyethylene 2,6-naphthalate film, wherein said coated polyethylene 2,6-naphthalate film has an F5 value in a machine direction of at least 1.5.times.10.sup.8 Pa, a Young's modulus in a machine direction of at least 5.9.times.10.sup.9 Pa, and a Young's modulus in a transverse direction of at least 5.9.times.10.sup.9 Pa, which capacitor has good moist-heat resistance and long-term stability.

Capacitor comprising polyethylene 2,6-naphthalate film

Disclosed herein is a magnetic recording medium comprising a polyester film layer, a coating type magnetic layer provided on one side of said polyester film layer, and a back-coat layer provided on the other side of said polyester film layer.

Magnetic recording medium comprising a polyester film substrate, a

There is disclosed a sublimation type thermal ink transfer recording material comprising a biaxially drawn film substrate consisting of a polyester base film and an applied primer layer of a reaction product of a polymerizable compound having carbon-carbon unsaturated bonds and a polyester, said substrate being drawn after a solution containing said reaction product is applied on the polyester film; a layer of sublimation type ink formed on said applied layer; and a slippery layer formed on the side opposite to said ink layer. This material has an ink layer which is not easily peeled off and has excellent image-forming ability.
