Abstract: The present invention is a pressure sensitive adhesive including a polyurethane polymer comprising a reaction product of an isocyanate, a (meth) acrylate-containing alcohol having at least one (meth)acrylate group and at least one alcohol group, and a polyol component having a defined solubility parameter of less than about 10; an oligomer comprising a multifunctional (meth)acrylate; and a photoinitiator. A peel adhesion of the pressure sensitive adhesive to glass decreases at least about 20% after being exposed to light radiation.

Abstract: An article comprising a first component having a first electrically conductive surface and a second component having a second surface. An adhesive composition comprising a cured polymerizable ionic liquid is disposed between the first electrically conductive surface and second surface and joins the first component to the second component. The polymerizable ionic liquid comprises an acid functional monomer and the conjugate acid of an imidazole compound. The effort required to separate the first component from the second component, as measured by work of adhesion per surface area, is reduced by application of a DC electric potential across the adhesive composition.

Abstract: Provided are amorphous polyolefin compositions that can be dispensed digitally as the core in a core-sheath construction. These formulations provide dependable adhesion to both polar and non-polar surface in addition to providing a high barrier to air and moisture which is beneficial in many applications. These formulations and the method of processing these formulations provide many benefits, including low VOCs, avoiding die cutting, design flexibility, achieving intricate nonplanar bonding patterns, printing on thin and/or delicate substrates, and printing on an irregular and/or complex topography, no need for release liners or low-adhesion backsize, and no need for a post-processing step.
