Abstract
An adhesive layer composed of at least an ionizing radiation curable resin binder, a thermoplastic resin binder and two or more matting agents having different average diameters is formed on a transparent polymer film to obtain a support film for a transparent conductive thin film. Alternatively, a transparent hard coat layer containing at least an ionizing radiation curable resin binder and,a matting agent having an average diameter of 1-15 &mgr;m, and an adhesive layer containing at least an ionizing radiation curable resin binder, a thermoplastic resin binder and a matting agent having an average diameter of 5-50 nm are formed on a transparent polymer film. The thus obtained support film is excellent in durability when the transparent conductive thin film is formed thereon and prevents occurrence of a Newton-ring, which is produced in a touch panel of the conventional liquid crystal display. The support film, when used in a touch panel of a color liquid crystal display, prevents glare of the color screen and is suitable for use in touch panels of both monochrome and color liquid crystal displays.
