Claims

[Scope of Claim for Utility Model Registration] (1) The release paper covering the adhesive surface of an adhesive sheet, adhesive board, etc. is provided with a line of brittle parts, such as perforations, so that it can be torn only in a certain direction, and In a release paper in which a cut at the end of the embrittled portion propagates along the embrittled line, (a) a base material subjected to the embrittlement process, (b) a resin film that covers the surface of the base material, and (c) the resin film. A release paper that can be torn only in a certain direction, and a release agent that coats the surface of the paper. (2) The surface of a base material that has been subjected to perforation-like (a series of perforated holes) embrittlement processing in multiple, parallel, or square shapes is coated with a resin film, and a release agent is applied to the surface of the film. A release paper that can be torn only in a certain direction as set forth in claim 1 of the utility model registration, characterized in that the paper is coated. (3) In the process of forming the resin film, a thin, easy-to-cut resin film is attached to a base material that has embrittled parts parallel to the fibers, such as by creating a difference in the longitudinal and lateral stretching directions. A release paper that can be torn only in a certain direction as claimed in claim 1 of the utility model registration, characterized in that the surface of the combined resin film is coated with a release agent such as silicone resin. (4) In a release paper in which a thin film is bonded to the surface of a paper base material and a release agent is coated on the surface of the film, multiple streak-like cuts that do not penetrate the base paper are made in parallel. A release paper that can be torn only in a certain direction as set forth in claim 1 of the utility model registration, characterized by:
