Abstract: A repositionable pressure-sensitive adhesive comprising from about 70% to about 99% solid, polymeric, acrylate, inherently tacky, infusible, solvent-insoluble, solvent-dispersible, elastomeric microspheres comprising at least one alkyl acrylate or alkyl methacrylate ester; and at least one polar monomer, and correspondingly, from about 30% to about 1% of a binder copolymer comprising an elastomeric polymeric backbone having pendant therefrom high Tg polymeric moieties.

Abstract: Microtextured elastomeric laminate tape comprising a laminate with at least one elastomeric layer and at least one thin skin layer, and an adhesive layer, preferably prepared by coextrusion of the layers followed by stretching the laminate past the elastic limit of the skin layers and then allowing the laminate tape to recover.

Abstract: A pressure-sensitive adhesive comprising an acrylate matrix, and swellable, infusible, insoluble, elastomeric acrylate microspheres, each of the microspheres having discrete boundaries, the microspheres and the matrix forming an interpenetrating polymer network within the boundaries of the microspheres.

Abstract: Hollow, polymeric, acrylate, infusible, inherently tacky, solvent-insoluble, solvent-dispersible, elastomeric pressure-sensitive adhesive microspheres having an average diameter of at least about 1 micrometer. Preferred microspheres are those wherein a majority of the hollow microspheres contain at least one of interior void having a diameter of at least 10% of the diameter of the microsphere.These hollow microspheres are useful as repositionable pressure-sensitive adhesives. The invention also provides pressure-sensitive adhesives consisting essentially of such hollow microspheres. Aqueous suspensions of these microspheres, processes for their preparation, spray repositionable pressure-sensitive adhesive compositions, and microsphere-coated sheet materials are also provided. Surprisingly, hollow microspheres of the invention show reduced or even eliminated adhesive transfer, in comparison with prior art repositionable pressure-sensitive adhesives which are based on solid microspheres.

Abstract: Hollow, polymeric, acrylate, infusible, inherently tacky, solvent-insoluble, solvent-dispersible, elastomeric, nitrogen-containing, acid-free pressure-sensitive adhesive microspheres having an average diameter of at least about 1 micrometer wherein a majority of the microspheres contain multiple interior voids, a majority of the voids having a diameter of less than about 10% of the diameter of the microsphere, the total of the diameters of the voids being at least about 10% of the diameter of the microsphere.These hollow microspheres are useful as repositionable pressure-sensitive adhesives.
