摘要： This invention provides a laminated film prepared by laminating at least one surface of a biaxially oriented polypropylene film (A) with an olefin polymer film (B) containing from 10 to 50% by weight of an ethylene component and the balance mainly comprising a propylene component, said olefin polymer film (B) having at least three peaks in the melting curve within the range of from 120.degree. to 165.degree. C. and a surface roughness Ra of from 0.2 to 1.5.mu., said laminated film being excellent in delustering quality, light transmittance, retention of delustering quality under heat and pressure, adhesion to metallized layers and to paper.This invention further provides a laminated film prepared by laminating a polymer film (C) containing from 1 to 40% by weight of an ethylene component and the balance mainly comprising a propylene component and having one or two melting peaks within the range of from 100.degree. to 165.degree. C. and a surface roughness Ra of below 0.15.mu., in the order of arrangement of (B)/(A)/(C), said laminated film being capable of readily providing a film having a mat finish metallic luster or a mirror finish metallic luster.

摘要： A film capacitor in which the unmetallized margin is provided with a semiconductive layer. The layer provides a parallel resistive path within the capacitor, itself, obviating the need for an external resistor. It also grades the electric field across the margin, i.e., makes the field more uniform, thus allowing the margin to be made narrower without electrical breakdown, permitting a reduction in the physical size of the capacitor. A refractory, semiconductive layer is provided between the metal layer and the dielectric film. The refractory layer accelerates the self-clearing process, by insulating the underlying dielectric film from the heat generated by the vaporizing metal, thus hastening vaporization and reducing the tendency of the dielectric film to carbonize. As a result, faults are cleared with substantially less energy consumption. Preferably, the refractory layer is also semiconductive, to reduce field emission effects, and thereby decrease the frequency of faults in the dielectric film.
