Curable pressure sensitive adhesive compositions comprising an acrylate copolymer,
a mono-acrylate oligomer, a multi-acrylate oligomer having from 2 to 5 acrylate
functional groups per molecule, and a photoinitiator, the adhesive exhibiting pressure
sensitive adhesive characteristics and forms at least a semi-interpenetrating polymer
network when cured; wherein the semi-IPN has an average molecular weight between
crosslinks (Mc) greater than about 3000, and the cured adhesive has
a peel strength greater than about 40 N/dm. Embodiments of the adhesive compositions,
when cured, are optically clear and resistant to heat and moisture.
