Abstract: The present invention provides a UV-curable pressure-sensitive adhesive composition, comprising: 81 to 97.5 parts of (meth)acrylate polymer having a carboxyl functional group by weight, the amount of the carboxyl functional group in the (meth)acrylate polymer having the carboxyl functional group being equal to or greater than 40 mmol/100 g; 2.5 to 19 parts of an epoxy resin by weight; 0.3 to 6 parts of a polyol by weight; and 0.05 to 5 parts of a photoinitiator by weight. The UV-curable pressure-sensitive adhesive composition has good anti-repulsion. The present invention further provides a UV-curable adhesive tape comprising the UV-curable pressure-sensitive adhesive composition.

Abstract: A method of forming a transfer film is described. The transfer film includes a template layer having a first major surface and an opposing second major surface. The second major surface includes a structured non-planar release surface. A backfill layer is disposed upon and conforms to the non-planar structured surface. The backfill layer includes a first cross-linked polymer and a plurality of multifunctional monomers, which cure via different and independent curing mechanisms.

Abstract: Transfer tapes include a releasing substrate and an adhesive layer adjacent to the surface of the releasing substrate. The adhesive layer includes a cured copolymer prepared from a reaction mixture that includes at least one alkyl (meth)acrylate, at least one ethylenically unsaturated silane, and an initiator. The adhesive layer is a pressure sensitive adhesive at room temperature and is convertible into a ceramic-like layer by bake-out at a temperature of from 170-500°.

Abstract: Adhesive articles include a substrate; and a hot melt processable pressure sensitive adhesive on the substrate. The hot melt processable pressure sensitive adhesive is a (meth)acrylate-based copolymer that is the reaction product of a reaction mixture that is free of acidic or basic monomers, and includes an alkyl (meth)acrylate, a hydroxyl-functional (meth)acrylate, and a photocrosslinker. The (meth)acrylate-based polymer is prepared in a thermoplastic package.
