Abstract
An improved wall decorating system is disclosed that utilizes a film comprising about 60-98% by weight ionomer resin that is a copolymer of ethylene and acrylic acid or methacrylic acid neutralized by a metal cation, the resin having a melt flow index greater than about 10 and about 2-40% by weight of a filler material, wherein the film has a thickness of between 0.050 and 0.127 mm. The wall decorating system also may include an improved adhesive comprising between about 60-100% by weight of hollow, polymeric, acrylate, inherently tacky, infusible, solvent-insoluble, solvent-dispersible, elastomeric pressure-sensitive adhesive microspheres having a diameter of at least 1 micrometer, and between about 0-40% by weight of a non-spherical polyacrylate adhesive.
