Title:
LAMINATED FILM
Document Type and Number:
WIPO Patent Application WO/2024/057660
Kind Code:
A1
Abstract:
The present invention provides a laminated film that has, on at least one surface of a thermoplastic resin base material, a resin layer X containing an antistatic agent and that satisfies all of the following (1) to (3). (1) The ratio (N/C) between elemental nitrogen and elemental carbon of the resin layer X, as calculated by a high-resolution rutherford backscattering spectroscopy (HR-RBS) measurement, and the average content ratio between nitrogen atoms and carbon atoms per 1 nm, as calculated on the basis of the thickness (nm) of the resin layer X, are each not less than 0.0030 [nm-1]. (2) The surface resistivity of the resin layer X is not more than 1.0×1010 Ω/□. (3) The surface free energy of the resin layer X is not less than 20.0 mN/m, but less than 30.0 mN/m. Provided is a laminated film that is excellent in releasability and antistatic properties of a surface layer and that can contribute to an improvement in performance of an electronic component or a battery without contamination by silicone and without loss of an antistatic material.
