Estimating the term…
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 θ, and the spectral intensity at 293.5 eV obtained by the partial electron yield method is defined as I(θ). 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.
A laminated film comprising a resin layer on at least one side of a resin base film, the resin layer being present at least one surface, wherein in an XAFS spectrum measured for the resin layer surface by the partial electron yield method, an X-ray absorption near edge structure (XANES) spectrum at the carbon K absorption edge satisfies I(15°)−I(90°)≥0.1 when the angle formed between the incident X-ray and the resin layer surface is defined as θ, and the spectral intensity at 293.5 eV is defined as I(θ).
A laminated film comprising a resin layer placed on at least one side of a resin base film, the laminated film having a tape peel strength of not more than 3.0 N/19 mm, and having a domain size of not more than 500 nm as observed in a modulus mapping image by AFM.
