PURPOSE: Provided are articles having slippable adhesives thereon which allow the articles to be positioned on a surface prior to adhesion. CONSTITUTION: An article is capable of being repositioned on a surface prior to being adhered to the surface. The article can either be removable only by wetting, scraping or steaming or can be removed by other methods. The article comprises: (a) a substrate having an adhering surface and a non-adhering surface; (b) a base adhesive layer covering at least a portion of the adhering surface; and (c) a low tack adhesive layer covering at least a portion of the base adhesive layer. The low tack adhesive layer contains an adhesive and microparticles. Preferably, the microparticles cause the low tack adhesive layer to have a surface for adhering that is not flat. The article is preferably a slippable sheet, such as wallcovering, which can be positioned, and aligned, on a surface before being adhered. |
