<p>An erasable product such as an erasable and rewritable label or an erasable sign comprises a base layer (2) and a transparent or translucent upper sheet (3) over the base layer (2) which provides a smooth and wrinkle-free top surface to the product. The upper sheet (3) and base layer (2) are releasably adhesive together under pressure applied manually on the upper sheet (3) such as writing pressure with a blunt stylus, to cause the upper sheet (3) and the base layer (2) to adhere in the localised region of pressure to display the writing in the case of a label. The upper sheet (3) can be moved sufficiently to separate it from the base layer (2) when a user's finger or thumb is wiped across the top surface of the upper sheet (3). The upper sheet (3) also extends over a wipe-start region (2a) where the upper sheet (3) and the base layer (2) are not adhesive together, over which wipe-start region (2a) a user's finger or thumb may be placed from which to begin said movement to separate the upper sheet (3) from the base layer (2).</p> |
