Provided are a flexible window film and a display apparatus comprising same, the flexible window film having a substrate layer, a buffer layer and a hard coating layer that are sequentially layered, wherein the buffer layer comprises, in a thickness direction, a first area in which the amount of an amide group gradually increases from the interface between the hard coating layer and the buffer layer, and a second area in which the amount of an amide group gradually decreases from the interface between the substrate layer and the buffer layer.

A laminate including a base material and a resin layer provided on at least one surface of the base material. The resin layer is formed of a heat- or active energy ray-curable resin composition, and an outermost surface of the laminate on the one surface side of the base material has an unevenness containing a wrinkle structure.

A method of applying a gas-impermeable coating includes forming a polyelectrolyte complex suspension. The polyelectrolyte complex suspension is applied to a substrate. The substrate having the polyelectrolyte complex applied thereon is treated. The treating reduces salt content of the polyelectrolyte complex. The treating results in a gas-impermeable coating being formed on the substrate.

The present invention relates to ethylene-vinyl alcohol copolymer particles, comprising an ethylene-vinyl alcohol copolymer having an ethylene unit content of 1 mol % or more and less than 20 mol %, a viscosity-average polymerization degree of 200 to 5000, and a saponification degree of 80 to 99.99 mol %, wherein a crystallinity in water Cw (30° C.) at 30° C. and a crystallinity in water Cw (70° C.) at 70° C. as determined by pulse NMR satisfy formula (I). There is thus provided ethylene-vinyl alcohol copolymer particles having excellent solubility in water and excellent gas barrier performance.

[PROBLEM] To provide an antifouling film equipped with protective film having an antifouling layer with excellent antifouling characteristics even after aging, and to a method for manufacturing same. [SOLUTION MEANS] An antifouling film equipped with protective film in which protective film is laminated on an antifouling layer of an antifouling film having an antifouling layer on a substrate film X, the antifouling film equipped with protective film being such that, when the protective film is detached from the antifouling film, a contact angle of water with respect to a surface of the protective film that had been in contact with the antifouling layer of the antifouling film is 90° to 115°. And also a method for manufacturing the aforementioned antifouling film equipped with protective film in which aging is carried out under certain temperature conditions while the protective film is laminated to a surface of the antifouling layer.

Provided is an antistatic polyimide-based film. More particularly, as an antistatic polyimide-based film for a window cover for protecting a surface of a display device, a window cover film having a protective film formed on the polyimide-based film provides an improvement to a problem of not being used as a film for a display window cover because a portion of the protective film remains on a base layer or a hard coating layer without being peeled off due to static electricity in the protective film or the base layer, or a hard coating layer, or the hard coating layer is peeled off with some or all of the protective film when the protective film is peeled off.
