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.
摘要:
Water-permeable, pressure-sensitive adhesives and adhesive constructions are characterized by a MVTR of at least 1,900 g/m2/day and low adhesive edge lift, even after 25 kGy gamma irradiation. The copolymers are formed from a plurality of acrylic monomers, preferably butyl acrylate, 2-ethylhexyl acrylate, hydroxyethyl acrylate, and optionally N-vinyl pyrrolidone.
摘要:
PSAs and PSA constructions, such as self-adhesive labels, are provided, and exhibit good slittability and reduced adhesive build-up in printers, including laser printers. In one embodiment, a PSA has a storage modulus at 1000 radians/s and 25° C. of about 5x106 dyne/cm2 or higher and a creep at 90° C. of about 125 or less. In one embodiment, the PSA is the polymerization product of a plurality of acrylic and other monomers.
摘要:
A decorative dry color laminate includes a dry color layer, a pressure-sensitive adhesive layer on one side of the dry color layer, and a carrier in releasable contact with the dry color layer on a side opposite from the pressure-sensitive adhesive (PSA). In use, the adhesive layer adheres the dry color laminate to the surface under application of pressure, and the carrier is peeled away to expose the dry color layer. Methods for providing a substantially permanent color effect on an architectural surface comprise delivering such an article to the architectural surface.

摘要:
Pressure sensitive adhesives produced from naturally occurring fats and oils are described. Also described are methods of producing the pressure sensitive adhesives. Generally, one or more naturally occurring fats or oils are epoxidized, and then reacted with certain alcohols or amines to thereby obtain the noted pressure sensitive adhesives.
