The invention is a pressure sensitive adhesive (PSA) composition, which is
the ultraviolet radiation (UV) cured reaction product of a
polyester-polyether-based urethane acrylate, one or more acrylate
monomers, and a UV photosensitizer. The polyester-polyether-based
urethane acrylate is the reaction product of between about 50 and 90 wt-%
of a polyester diol having a molecular weight ranging from about 500 to
3200; between about 10 and 50 wt-% of a polyether polyol having a
molecular weight ranging from about 1000 to 6000; between about 1 and 5
wt-% of a hydroxy-functional acrylate; and a polyisocyanate.
