A pressure sensitive adhesive composition is described comprising at least 50 wt-% of polymerized units derived from alkyl meth(acrylate) monomer(s); and 0.2 to 15 wt-% of at least one cross-linking monomers comprising a (meth)acrylate group and a C-Colefin group, the olefin group being optionally substituted. In another embodiment, an adhesive composition is described comprising a syrup comprising i) a free-radically polymerizable solvent monomer; and ii) a solute (meth)acrylic polymer comprising polymerized units derived from one or more alkyl (meth)acrylate monomers; wherein the syrup comprises at least one crosslinking monomer or the (meth)acrylic solute polymer comprises polymerized units derived from at least one crosslinking monomer, the crosslinking monomer comprising a (meth)acrylate group and a C-Colefin group, the olefin group being optionally substituted. In yet other embodiments, methods of preparing adhesive compositions are described.

An aerosol is described comprising a composition comprising an acrylic block copolymer, a solvent, and a propellant. An article is described comprising the aerosol contained within a pressurized containment vessel comprising a valve. An aerosol mist is also described comprising droplets of an adhesive composition, wherein the adhesive composition comprises an acrylic block copolymer, a glass transition temperature modifier, and optionally an additive.

Disclosed is a release material applied to a sheet material that provides for temporary repositioning of an adhesive over the release material. Over time the adhesion between the release material and the applied adhesive builds such that the adhesive cannot be removed from the release material without damaging the underlying sheet material. The release material includes an free nitrogen containing basic group. The release material is dispersed on a flexible substrate and the release material allows for repositioning when contacted with a pressure sensitive adhesive, which includes a free carboxylic acid group, for at least 1 minute and not more than 10 minutes.

A liquid ink repellent coating adapted to prevent transfer of fluid image forming ink droplets between imaged sheets in a stack of multiple printed impressions. The repellent coating comprises a polymeric composition having a surface energy less than about 30 mJ/m and an insoluble particulate filler as a matting agent.
