ABSTRACT:
This invention provides a paper based wallcovering having an optional decorative surface and coated on the back surface thereof with a moisture resistant, elastomeric barrier layer overcoated with a layer of a removable tacky pressure sensitive adhesive, the outwardly facing surface being coated with a moisture-resistant barrier coating of a synthetic resin composition having release properties. The pressure-sensitive adhesive coating and the synthetic resin are so chosen that the protective coating of the synthetic resin on the decorative surface acts as a release coat for the adhesive and the barrier layers are so chosen that the expansion and contraction of the paper substrate under the influence of environmental moisture is minimized and/or accommodated.
