Abstract
An anti-static hard coat film is easy to manufacture, has a high total light transmission, achieves favorable viewability for displayed images, and has a superior balance between an anti-static effect and a resistance to scratch. A hard coat layer made of an ionizing radiation-curable resin and an anti-static layer, which is about 0.03 to 2 μm thick and is made of ionizing radiation-curable resin that includes anti-static particles with an average particle diameter of about 0.01 to 2 μm, are formed in order on a base film, and the Taber abrasion resistance is set at 25 or below as measured in accordance with JIS K5400.
Claims12
An anti-static hard coat film, comprising
- a base film;
- a hard coat layer, which comprises an ionizing radiation-curable resin, and which is obtained by ionizing radiation curing of about 100 mJ/cm2 or below;
- and
- an anti-static layer, which is about 0.03 to 2 μm thick and which comprises an ionizing radiation-curable resin that includes anti-static particles with an average particle diameter of about 0.01 to 2 μm, and which is obtained by ionizing radiation curing of about 500 mJ/cm2 or above;
- wherein the hard coat layer and the anti-static layer are disposed in order on the base film, and the anti-static hard coat film has a Taber abrasion resistance of 25 or below as measured in accordance with JIS (Japanese Industrial Standards) K5400.
A method of manufacturing an anti-static hard coat film, comprising:
- a first step of forming a hard coat layer, composed of an ionizing radiation-curable resin, on a base film by irradiating the ionizing radiation-curable resin with ionizing radiation of about 100 mJ/cm2 or below;
- and
- a second step of forming an anti-static layer, which is about 0.03 to 2 μm thick and is made of an ionizing radiation-curable resin that includes anti-static particles with an average particle diameter of about 0.01 to 2 μm , by ionizing radiation curing of about 500 mJ/cm2 or above, on top of the hard coat layer;
- and setting a Taber abrasion resistance of the anti-static hard coat film at 25 or below as measured in accordance with JIS (Japanese Industrial Standards) K5400.
