  • Publication number: 20150030850
    Abstract: The purpose of the present invention is to provide a re-peelable protective adhesive film having excellent adhesion between a re-peelable adhesive layer and an antistatic layer, having peeling charging preventive properties, and in which air bubbles are unlikely to be incorporated when the film is affixed to a surface of panel or display. This re-peelable protective adhesive film has an antistatic layer on one surface of a transparent resin film, and has re-peelable adhesive layer on the antistatic layer. The antistatic layer is obtained by forming a film from a mixture of an electroconductive polymer and an acrylic emulsion, and the electroconductive polymer and acrylic resin are included in the layer. The re-peelable adhesive layer includes a urethane adhesive and an isocyanate curing agent.

  • Patent number: 8236406
    Abstract: A fingerprint easily erasable film formed by providing a resin layer on a substrate, in which surface of the resin layer is matted and which is formed so that the surface of the resin layer should show a wet tension (JIS-K 6768:1999) of 25 mN/m or higher. Preferably, the resin layer has a surface roughness of 0.2 to 2.0 ?m in terms of the ten point mean roughness Rz (JIS-B 0601:1994). The resin layer preferably contains an ionizing radiation curable resin and a matting agent, more preferably, two kinds of matting agents having different average particle diameters. On the fingerprint easily erasable film having such a configuration, ingredients of fingerprint are unlikely to adhere, and even if ingredients of fingerprint adhere, the ingredients of fingerprint can be removed substantially completely or to such a degree that they cannot be visually observed by wiping with cloth or the like.

  • Patent number: 6602596
    Abstract: There is provided a light diffusion sheet comprising a light diffusion layer formed on a transparent substrate and containing a binder resin and resin particles that impart an uneven surface, wherein the uneven surface of the light diffusion layer exhibits an arithmetical mean deviation of 2.0 &mgr;m or more in three-dimensional surface roughness measurement and/or ten point height of irregularities of 10.0 &mgr;m or more in three-dimensional surface roughness measurement. This light diffusion sheet is high luminance in the front direction, is excellent in light-diffusing property, and is resistant to damage.
