Abstract
Radiation-curable, tackifier-free compositions are provided which contain: (i) a blend of certain acrylate esters and monoethylenically-unsaturated copolymerizable monomers; (ii) certain .alpha.-olefin polymers; and (iii) a photoinitiator and optionally, a crosslinker. Pressure-sensitive adhesives having good adhesion to both low and high energy surfaces as well as possessing excellent low and high temperature performance properties are prepared by exposing the radiation-curable compositions to light having a wavelength in the range of from about 280 to 400 nm.
