Embodiment 1

[0061] Poly(ethylene terephthalate) (PET) film (approximately 5 mil thickness) with a matte hard coat was purchased from Kimoto Tech, Inc. (Cedartown, GA). A layer of 19 nm indium tin oxide (ITO) and a layer of 20 nm of SiO were then deposited on top of the hard coat surface of the PET film by DC sputtering. x . Mix the three solutions together to make a coating solution. Table 1 shows the chemical compositions of these three solutions and the resulting coating fluids.

Abstract

An antireflection film and method of making same includes a substrate having a first surface and a second surface, an inorganic layer deposited on the first surface of the substrate, and an optically active polymer layer formed by curing a curable composition in situ on the inorganic layer, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 nm to 700 nm and a thickness of from about 20 nm to about 200 nm, and an adhesive layer deposited on the second surface of the substrate.

Description

field of invention [0001] The invention relates to a peelable anti-reflection film, in particular to an anti-reflection film for information display. Background of the invention [0002] The advantage of providing anti-reflective films for various parts, such as lenses, cathode ray tubes, optical displays, window films and windshields, is that it can reduce the amount of light reflected by the surface of the part, thereby reducing or eliminating the effects of these reflected light. Overlay formed. Additionally, in various fabrications, such as optical displays, it would be beneficial to provide protective and / or anti-smudge films to reduce contamination or damage to the fabrication surface. For example, optical displays used in devices such as personal digital assistants ("PDAs"), mobile phones, touch screens, flat-panel and / or other productions. Therefore, face oil can seriously affect the contrast, color saturation or brightness of a light display. Scratches, scuffs, ...
