Except for the above, the films of Examples 1 to 8 were prepared in the same manner as in Examples. In Comparative Example 2, a film was produced without providing a coating layer.
- Example 1 the resin for the intermediate layer and the resin for the surface layer are used in common, and each chip containing polyester A: B: C at a ratio of 85: 7: 8 is used. I put it in both machines. Thereafter, a film was formed in the same manner as in Example 1 to prepare a biaxially oriented film. This film is a coextrusion monolayer film. The total thickness was 25 m. When forming a melt sheet during film formation, a phenomenon in which sublimates gradually adhere to the cooling drum (not observed at all in Example 1) was observed and produced as it was for a long time. It was impossible. The characteristics of this film are shown in Table 2. Since the same fine particles as in Example 1 were added to the intermediate layer at the same concentration, the film became cloudy with high film haze.
- the metal-added metal oxide particles or the metal-added metal oxide particles having no haze, excellent light-shielding properties and heat insulation properties, and not contaminating the production machine due to dye sublimation or the like.
- a film having excellent adhesion to a resin layer or a hard coat layer containing metal oxide particles can be provided, and its industrial value is high.
