20090011254 | RELEASE FILM AND METHOD OF PRODUCING SAME - Provided is a release film, including a plastic film substrate, a surface modification layer formed on a single surface or both surfaces of the plastic film substrate by radiating a flame of a fuel gas including an organosilicon compound onto the single surface or both surfaces, and a silicone release layer composed of a cured product of a curable silicone composition, in which the silicone release layer is provided on top of the surface modification layer. The release film exhibits excellent adhesion between the silicone release layer and the plastic film substrate. The release film is produced at low cost and at a high level of productivity by a method including: forming the surface modification layer on a single surface or both surfaces of the plastic film substrate by radiating a flame of the fuel gas onto the single surface or both surfaces, and forming the silicone release layer on top of the surface modification layer by applying the curable silicone composition to the surface modification layer and then curing the composition. | 01-08-2009 |
