Abstract
An adhesive composition, useful for making a repositionable sheet, which is made up of a mixture of: (a) a polymer prepared by aqueous suspension polymerization of at least one monomer selected from an acrylate, a methacrylate and acrylic acid, the polymer having a geometric mean particle size ranging from about 30 to about 100 microns; and (b) a polymer prepared by aqueous suspension polymerization of at least one monomer selected from an acrylate, a methacrylate and acrylic acid, the polymer having a geometric mean particle size ranging from about 4.1 microns up to about 30 microns.
