    Abstract: The present invention provides a laminated film (31) where a coating layer (22) containing organic particles (12) is provided on the surface of a base film (21) and the ratio (SRz/d) of the surface roughness (SRz) of the coating layer (22) surface and the coating thickness (d) is 12.5 or higher, wherein the organic particles (12) are made from a thermoplastic resin containing ether bonds, and the coating layer (22) is made from a binder resin (11) containing at least one type of a sulfonic acid group, carboxylic acid group, or hydroxyl group, or a salt thereof, and also provides a method for manufacturing the same. The present invention can provide at low cost a laminated film (31) that does not shed organic particles (12) and that has a coating layer (22) containing beads or particles having a large uneven surface.

    Abstract: A film excellent in heat resistance, dimensional stability to heat, and mechanical properties, especially a film capable of satisfying requirements such as higher strength necessary for base-film thickness reduction, improved dimensional stability to heat and improved mechanical properties in use atmospheres, and enhanced heat resistance and improved dimensional stability to heat which meet the needs of the electrical and electronic fields for size reduction and multi-function. It is obtained by incorporating transition metal oxide particles into a thermoplastic resin and forming the composition into a film which is a biaxially oriented thermoplastic film having a melting point higher than that of the thermoplastic resin used. Preferably, when the biaxially oriented thermoplastic resin film is analyzed with a differential scanning calorimeter (DSC), the difference between the peak temperature for the quantity of heat of fusion in the 1st run (melting point T1) and the peak temperature for the quantity of heat of fusion in the 2nd run (melting point T2) satisfies the following relationship. 2°C ≤ T1-T2 ≤ 30°C Alternatively, the biaxially oriented thermoplastic resin film containing transition metal oxide particles incorporated therein is regulated so as to have a coefficient of in-plane orientation of 0.120 or higher and lower than 0.280.

    Abstract: [PROBLEMS] To provide: a novel, industrially useful acrylic resin film excellent in all of transparency, weatherability, heat resistance, and toughness, in view of the fact that there has been no acrylic resin film having such properties; an acrylic resin film which comprises the acrylic resin film having, e.g., a hard coating layer formed on at least one side of the film and further having an antireflection film formed on at least one side of the film; and an optical filter comprising this film. [MEANS FOR SOLVING PROBLEMS] The former acrylic resin film comprises an acrylic resin having units of glutaric anhydride and acrylic elastomer particles incorporated in the resin, and has a total light transmittance of 91% or higher, a haze of 1.5% or lower, a value of the number of folding operations of 20 or larger, and a degree of thermal shrinkage less than 5% in at least one of the machine direction and the transverse direction in a thermal shrinkage test.

    Abstract: PROBLEM TO BE SOLVED: To provide a laminated polyester film which has a large flexural strength even with the thickness lessened and which is excellent in heat resistance and also excellent preeminently in the form stability in a processing process and in an environment of use for a tape. SOLUTION: The laminated film has a structure of lamination of at least three layers or more, and the surface layer part thereof is a film layer constituted of a thermoplastic resin (A), while the central part comprises at least one film layer or more constituted of a thermoplastic resin (B) different from the thermoplastic resin (A). The glass transition temperature of the thermoplastic resin (A) is higher than that of the thermoplastic resin (B), and a flexural strength index converted into a thickness 5 μm in at least either the longitudinal or width direction of the film is 6 ×10-3-30×10-3 N/m.
