摘要： An oriented syndiotactic polystyrene-based film composed of an oriented film made of a syndiotactic styrene polymer and an adhesiveness-improving layer formed from a specific water - dispersible resin on at least one surface of the oriented film, which is excellent in the tight adhesion between the oriented film and the adhesiveness-improving layer, the adhesion between the adhesiveness-improving layer and an ink layer or laminate layer applied thereon, economical efficiency, recyclability, and environmental compatibility in production. It is particularly preferable that the film be produced by applying the aqueous dispersion of the water -dispersible resin on unstretched or uniaxially stretched film to form the adhesiveness-improving layer, stretching the obtained laminate uni- or bi-axially at least one time, and then heat-treating the resulting laminate.

摘要： [PROBLEMS] To provide a polyimide film suitable for use as a base material film of electronic components that excels in thermal stability, rigidity and high-frequency characteristics and also excels in heat distortion stability such that failure due to curling would not occur even when various functiona l layers are superimposed thereon while heating. [MEANS FOR SOLVING PROBLEMS] A polyimide film wherein the in-plane orientation coefficient of the film, measured by X-ray diffractometry, is in the range of 0.79 to 0.89, the difference between the degree of surface in-plane orientation with respect t o one major surface of the film and the degree of surface in-plane orientation with respect to the other major surface of the film being 2 or less, and wherein the degree of curling of the film is 5% or less, is obtained by imidizing a polyimide precursor film of specified imidization ratio.
