发明名称 Fingerprint easily erasable film
摘要 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 mum 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.
