Abstract: A self-adhesive patch formed of leather, bonded leather or synthetic leather for application to furniture, garments and luggage is provided with a debossed peripheral region which is coplanar with the reverse side of the patch and denser than the remainder of the patch. When applied, the edge of the patch is therefore lower than the main body of the patch and less likely to be unpeeled from the item to which it is attached.

Abstract: A multilayer thermoformable film to protect the surface of a workpiece includes an underlayer having first and second faces. The underlayer is made from an adhesive material configured to adhere to the surface of the workpiece by the first face. At least one layer of polymer material is attached to the second face of the adhesive underlayer. The layer of polymer material is resistant to erosion by solid particles and to erosion by liquid particles. It is formed from a polymer material chosen from a polyurethane, a polyether ether ketone and a polyethylene having a very high molecular weight, with a Shore D hardness of between 50 and 65 D. A method of surface protection of the workpiece includes thermoforming the film in a shape adapted to match the shape of at least a portion of the workpiece and applying the film thermoformed onto the surface of the workpiece.

Abstract: The present application relates to a pressure-sensitive adhesive composition, a protective film, an optical element and a display device. The pressure-sensitive adhesive composition of the present application has excellent storage stability, exhibits an appropriate low-speed and high-speed peel forces after the cross-linked structure is formed, and has excellent balance of both. Furthermore, the pressure-sensitive adhesive formed by the pressure-sensitive adhesive composition does not leave contaminants in the adherend after peeling, while exhibiting re-detachability. Accordingly, when the pressure-sensitive adhesive composition is applied to, for example, a protective film, it is also advantageous in terms of high-speed processes by being easily peeled off upon high-speed peeling as well as it exhibits an excellent protective effect, thereby being capable of exhibiting excellent antistatic characteristics.
