  • Publication number: 20240043640
    Abstract: A laminated film including a resin layer on at least one side of a resin base film, the resin layer being present at least one surface, wherein the X-ray absorption near edge structure (XANES) spectrum at the carbon K absorption edge at the resin layer surface satisfies I(15°)?I(90°)?0.1 when the angle formed between the incident X-ray and the resin layer surface is defined as ?, and the spectral intensity at 293.5 eV obtained by the partial electron yield method is defined as I(?). Provided is a laminated film as a release film to be used in an application that is carried out by coating the film with a coating liquid including a solvent, drying and solidifying the coating liquid, and then peeling off the solidified coating, which laminated film shows excellent applicability and an excellent peeling property, and does not show delamination of the surface layer even after a heating process.

  • Patent number: 11851542
    Abstract: A laminated film has a resin layer on at least one surface of a polyester film, in which the resin layer is on at least one surface layer, the water contact angle of the resin layer is 85°-100°, inclusive, and |H2-H1|?1.0 (%) is satisfied, H1 (%) being the haze of the laminated film and H2 (%) being the haze of the laminated film after being immersed in a solvent and subjected to a rub test. This laminated film has excellent coating and releasability properties with respect to ceramic slurry.
