Abstract: Sheet-like material, such as wallpaper, posters or labels, can be stripped dry from surfaces to which they have been bonded after adhesive layers (applied in an aqueous medium) have dried. Adhesives which contain film-forming, water-soluble or water-swellable polymers are used. Separate layers containing two different adhesive polymers, particularly polysaccharide derivatives, are provided between the sheet-like material and the surface to which it is to be bonded, one of the two layers containing at least one non-ionic polymer and the other containing at least one ionic polymer. The invention includes the use of these adhesives (containing different film-forming, water-soluble or water-swellable polymers) in preparing dry-strippable sheet-like material and sheet-like material, such as wallpaper, posters or labels, having adhesive layers which can be reactivated by moistening with water and which comprise these adhesives.
