Abstract: The present disclosure provides an article. In an embodiment, the article includes a first substrate and an adhesive layer in contact with the first substrate. The adhesive layer contains an adhesive composition. The adhesive composition includes (i) an acrylic polymer composed of polymerized units of (a) a first monomer that is a C4-C18 alkyl acrylate and (b) a second monomer selected from acrylic acid, methacrylic acid, and a C1-C3 alkyl acrylate optionally containing a hydroxyl group. The adhesive composition also includes (ii) at least one inorganic neutralizer, and (iii) at least one surfactant. The article includes a second substrate in contact with the adhesive layer.

Abstract: Provided is a pressure sensitive adhesive article comprising (a) a substrate (Sa) (b) in contact with the substrate (Sa), a layer (Lb) of a pressure sensitive composition (Cb) that comprises one or more acrylic polymer (POLb) having Tg of 20° C. or lower, and (c) in contact with the layer (Lb), a layer (Lc) that comprises, (i) one or more acrylic polymer (POLc1) having Tg of 20° C. or lower, and (ii) one or more acrylic tackifier polymer having Tg of ?10° C. or higher. Also provided are a method of making the pressure sensitive adhesive article and a bonded article made by using the pressure sensitive adhesive article.

Abstract: The present invention is a pressure sensitive adhesive for use on a wallcovering to cover a surface such that the wallcovering is repositionable and removable without damage to the surface. The pressure sensitive adhesive is made by combining a plurality of water based acrylic emulsions and a plurality of hollow glass bubbles having a density and size to be present at the surface of the pressure sensitive adhesive and reduce initial tack to allow movement of the wallcovering on the wall surface. The hollow glass bubbles halve a density within the range of 0.05 to 0.10 g/cc and a size within the range 40 to 177 microns in diameter. Additives can be added to the pressure sensitive adhesive of the present invention such as surfactants, defoamers, thickeners, and tacking resins. The pressure sensitive adhesive is applied to a wallcovering and dried to evaporate the water content.
