Abstract
Disclosed is an antiglare film having excellent durability. The antiglare film is disposed on the front of a display device and comprises a transparent plastic film and, formed on the transparent plastic film, at least an antiglare layer having fine concaves and convexes on its surface, wherein the antiglare layer is formed of a transparent resin and satisfies requirements that: (1) the surface of the antiglare layer has a three-dimensional ten-point mean roughness of 0.9 μm to 3 μm; and (2) the mean spacing between adjacent profile peaks on a three-dimensional roughness reference plane is 20 μm to 50 μm.
Claims8
A process for producing an antiglare film, comprising the steps of:
- bringing a transparent plastic film in a molding tool having on its surface concaves and convexes which have an inverted shape of fine concaves and convexes of the antiglare layer to be formed;
- placing an ionizing radiation-curable resin between the transparent plastic film and the molding tool;
- applying an ionizing radiation to the ionizing radiation-curable resin to cure the ionizing radiation-curable resin and to adhere the cured product of the ionizing radiation-curable resin to the transparent plastic film, thereby forming an antiglare layer having fine concaves and convexes on its surface;
- and
- separating the transparent plastic film with the antiglar layer formed thereon from the molding tool,
- said antiglare layer satisfying requirements that:
- (1) the surface of the antiglare layer has a three-dimensional ten-point mean roughness of 0.9 μm to 3 μm;
- and
- (2) the mean spacing between adjacent profile peaks on a three-dimensional roughness reference plane is 20 μm to 50 μm.
