Abstract
Abstract A sheet material which can be firmly adhered to a surface, and yet readily removed thereform, without the necessity of pre-wetting and without damaging the surface is prepared by coating one side of a base sheet with an adhesive composition containing a tacky, pressure sensitive adhesive, a wax, water, and an emulsifier. The adherable, yet removable nature of the sheet material does not degrade, but instead is maintained, over time. The sheet material is suitable for use as wallpaper, shelving paper, posters, note pads, labels, and the like.
