    摘要: Acrylic, self-adhesive postage stamps are provided and include a flexible facestock bearing an acrylic pressure-sensitive adhesive (PSA), protected by a release liner. The acrylic PSA is a tackified or inherently tacky polymer formed from a plurality of monomers comprising, based on the total weight of monomeric composition, essentially of (i) 9 to 40% isobornyl acrylate and (ii) 50 to 91% of one or more alkyl acrylates.
