ABSTRACT:
An acrylic terpolymer pressure-sensitive adhesive comprising a photopolymerized polymer containing an alkyl acrylate monomer, the alkyl groups of which have an average of 6 to 12 carbon atoms, a first polar copolymerizable monomer selected from strongly polar monomers, and a second polar monomer selected from the group consisting of strongly polar monomers and moderately polar monomers, a hydrogenated rosin ester tackifying agent, and a photoinitiator, wherein the adhesive has a lower glass transition temperature as measured by Dynamic Mechanical Thermal Analysis than would an identical acrylic terpolymer adhesive omitting the tackifying agent.
