Abstract
There is provided a radiation-curable, pressure-sensitive-adhesive layer formed of at least one monomer having a glass-transition temperature greater than about -25.degree. C. and an entanglement molecular-weight less than about 20,000; at least one monomer having a glass-transistion temperature less than about -25.degree. C. and an entanglement molecular-weight greater than about 20,000; and at least one tackifier monomer having a glass-transistion temperature greater than -25.degree. C. and an entanglement molecular-weight of at least about 20,000 and present in an interpolymerized amount sufficient to form an interpolymer having a glass-transition temperature less than about -25.degree. C. and an entanglement molecular-weight greater than about 20,000. Cure is preferably by electron beam, and a multifunctional monomer is preferably provided to improve shear.
