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 nonomer.
L'invention concerne des constructions et des compositions d'adhésifs autocollants (PSA) détachables, améliorés, contenant un copolymère PSA acrylique en émulsion issu d'une pluralité de monomères acryliques, et au moins un monomère de réticulation composé de cire et d'un plastifiant. Les forces de détachement nécessaires pour enlever les constructions d'une variété de substrats sont notablement inférieures à celles nécessaires pour enlever des compositions comparables ne contenant pas de monomère de réticulation.
