FIG. 2 is a part of a sectional view of a film for a film capacitor, in which 21 is a base film, 22 and 23 are vapor-deposited metal, and 24 and 25 are dielectrics. Aluminum is first deposited on a wide and long base film 21 at a predetermined position while leaving a margin width.
After vapor-depositing so as to be 2, the aluminum is vapor-deposited so as to become the vapor-deposited metal 23 also on the back side thereof at a predetermined portion displaced by the width of the margin. The dielectric substance 24 is applied so as to extend over a part of the base film 21 and the vapor-deposited metal 22. Similarly, the dielectric 25 is applied to the opposite surface at a position facing the dielectric 24 to form a dielectric film for a capacitor. The dielectric is formed by dissolving a polymer compound in an organic solvent, applying a thin film coating, and then drying the organic solvent to form the compound as a dielectric.

It is possible to form a thin film having a thickness of m or less, and since the curing shrinkage is small, it is possible to obtain a coating film for capacitors in which wrinkles are less likely to occur.

水素が好ましい。As a characteristic of each component, dimethylol tricyclodecane diacrylate (Chemical formula 1) has a low dielectric loss angle (tan δ) but a viscosity of about 150 Pa · s.
And the diacrylate having the structure shown in (Chemical Formula 2) has a viscosity,
Although it has a low dielectric loss angle (tan δ) and a heat resistance of 170 ° C or higher, it has some water absorption. In the case of diacrylate having n of 6 or less, the curing shrinkage is large and the dielectric loss angle is 0.01.
5, the film capacitor of the present invention cannot withstand use. Further, when n is 14 or more, thin film coating cannot be performed and the curing rate is remarkably slow, and as a result, saturated aliphatic hydrocarbon having n of 7 or more and 13 or less is preferable.

点がやや低いという欠点がある。The above-mentioned two-component mixed paint is slightly inferior in dielectric loss angle (tan δ) and water absorbency to conventional paints. Therefore, when monoacrylate having a cyclic skeleton is added as the third component, the water absorption becomes low and the dielectric loss angle (tan δ) becomes good. The monoacrylate-added three-component paint has a low viscosity, so that it is easy to work and high-speed operation is possible, so that the running cost can be reduced. Further, the temperature characteristics of the coated film capacitor are better than those of the polyethylene terephthalate base film. Generally, a monoacrylate having a cyclic skeleton has a low viscosity and a low dielectric loss angle (tan δ) and hardly absorbs water, but has a drawback that the flash point is slightly low.

Since it is solvent-free, a film with less variation in thickness and unevenness can be formed, and pinholes do not occur when the solvent volatilizes, so that the withstand voltage characteristics can be improved. Further, since curing shrinkage due to ultraviolet irradiation is smaller than shrinkage due to solvent volatilization, the film does not have wrinkles and dimensional accuracy is good, so that a high quality coating film can be formed. Further, since the diacrylate has a high relative dielectric constant, the capacity per film is improved as compared with the conventional one.
