    • A polyimide-based polycondensate which may be used as an insulation film by coating a copper foil with the polycondensate and by heating the coated copper foil, which insulation film does not warp the foil, as well as a production process thereof, is disclosed. The polycondensate according to the invention is a solvent-soluble polycondensate containing a benzoxazole component having a carboxylic group and an imide component having a phenolic hydroxyl group, which is obtained by dehydration-condensing one or more tetracarboxylic dianhydrides with one or more aromatic diamines having an amino group and a phenolic hydroxyl group, the amino group and the phenolic hydroxyl group being located at ortho positions with respect to each other, by heating the one or more tetracarboxylic dianhydrides and the one or more aromatic diamines at 150° C. to 220° C. in the presence of an acid catalyst.

    • A color cathode ray tube includes an evacuated envelope having a generally rectangular panel portion, a narrow neck portion having a circular cross-section and a funnel portion tapering down from a panel-portion side thereof toward a neck-portion side thereof for connecting the panel portion and the neck portion, a three-color phosphor screen formed on an inner surface of the panel portion, an electron gun housed in the neck portion, and an internal conductive film extending from an inner wall of the neck portion to an inner wall of the funnel portion. The funnel portion is provided with a yoke-mounting portion of generally truncated quadrilateral-pyramidal shape for mounting a beam deflection yoke therearound on the neck-portion side of the funnel portion. The internal conductive film is formed of a first part and a second part, the first part is formed of graphite, metallic oxide and potassium silicate, and the second part is formed of graphite and potassium silicate. The first part extends from the neck portion in the vicinity of a forward end of the electron gun to a position in the yoke-mounting portion spaced a distance in a range of 60 mm to 150 mm from a splice line between the neck portion and the funnel portion, and the second part overlaps with the first part at opposing ends thereof and extends to a vicinity of a seal line between the funnel portion and the panel portion.
