Abstract RU 2796471 C2

FIELD: multilayer film.

SUBSTANCE: invention relates to a multilayer film for displays and a method for its manufacture. The multilayer display film includes a resin layer laminated on at least one surface of the base film. The multilayer film is characterized in that: the base film is a semi-aromatic polyamide film which has been subjected to at least uniaxial stretching; the resin layer has a thickness of 0.03 to 0.5 mcm; the surface of the resin layer has a dynamic friction coefficient of 0.7 or less in the atmosphere at 23°C×50% relative humidity (RH); and the tight adhesion between the base film and the resin layer, according to the grid cut method described in JIS K 5600, is 95% or more.

EFFECT: invention improves the adhesive strength between the base film and the hard cover layer, and provides a multilayer film in which a resin layer is layered on the base film, on which a hard cover layer with excellent adhesive strength can be layered.
