Abstract
Improved, removable PSA compositions and constructions contain an emulsion acrylic PSA copolymer of a plurality of acrylic monomers and at least one multifunctional crosslinking monomer, compounded with a wax and a plasticizer. Peel forces required to remove the constructions from a variety of substrates are notably smaller than those required to remove comparable compositions containing no crosslinking monomer.
