摘要: The objective of the invention is to solve the problems described above. Specifically, the invention aims to provide highly heat resistant and dimensionally stable polyester film that is so high in formability as to maintain a low stress and a high ductility during forming processes.
The invention provides a polyester film comprising ethylene glycol component that accounts for 60 mol% or more of the glycol components in the polyester film, containing a crystal nucleating agent up to 0.01 to 5 mass% relative to the entire polyester film that accounts for 100 mass%, and having a crystal melting energy, ΔHm, of 5 to 35 J/g.-

摘要: 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.
