<p>This invention relates to transferable pressure-sensitive adhesive films in the form of a pad. Dry pressure-sensitive adhesive films known in the art suffer from several disadvantages, e.g., the need to dispense from a special dispenser, the generation of waste material, the limitation on possible shapes of the adherent area. It would be desirable to develop a dry pressure-sensitive adhesive film that would not have the foregoing disadvantages. This invention provides a dry transferable pressure-sensitive adhesive film, which in the form of a pad, and is coated on a plurality of stacked, bothsided but differently adhesion-release treated backing materials, while forming adhesive-free areas on each backing materials and being in each case, in contact with the other side of the adjacent backing material in the pad, whereby the most upper backing sheet of the pad can be readily peeled off from the pad together with the attached adhesive film and can be pressed onto a substrate, on which an adherent surface film will remain on peeling off the backing material from the adhesive film.</p> |
