ANTIREFLECTION MATERIAL AND POLARIZING FILM USING THE SAME

WIPO Patent Application WO/2000/022461

A1

An antireflection material comprising a transparent substrate, a hard coating layer which is provided, directly or via another layer, on one or both surfaces of the substrate, and an antireflection coating which is provided on the surface of the hard coating layer and has a refractive index lower than that of the hard coating layer, wherein the hard coating layer comprises (1) a polymer containing a (meth)acrylate compound having a fluorene skeleton as a component thereof, or (2) a polymer containing a urethane (meth)acrylate compound as a component thereof and ultra fine particles having a high refractive index, or (3) a radiation- and/or heat-curing resin and surface treated ultra fine particles of titanium dioxide; and a polarizing film using the same. The antireflection material and the polarizing film exhibit excellent antireflection properties and thus can be used for preventing an external light such as the sunshine and the light from a fluorescent lamp from reflecting into a display and providing a clear image free from screen glare or the like without lowering the contrast in an image, and further have good optical stability and excellent resistance to abrasion, chemicals and stains.
