Patent number: 7641946Abstract: An adhesive film prevents static charge on peeling generated when removed from an adherend and also improves adhesion between a base material and an adhesive layer, where an under coat layer containing an organometallic is formed on the base material and then an adhesive layer is formed on the base material. Alternatively, an adhesive film showing high adhesion with a glass substrate, and including an antistatic layer, which prevents static charge on peeling generated when the surface protective film is removed, and improves adhesion between a base material and an adhesive layer, where the adhesive film includes a base material, an adhesive layer made of a water dispersible adhesive including, and an antistatic layer, containing a water soluble or water dispersible conductive material, interposed between them, and the adhesive film is stuck onto an image display device.Type: GrantFiled: July 20, 2006Date of Patent: January 5, 2010Assignee: Nitto Denko CorporationInventors: Mika Kanamaru, Kenichi Okada, Toshitaka Takahashi
