Abstract

The present invention relates to liquid dual curing (moisture) and photocuring adhesives which are optically transparent/clear. More particularly, the present invention relates to liquid optically transparent/clear adhesives having at least one photo- and/or heat-curable polyolefin-based oligomer, with or without a moisture-curable polyolefin-based oligomer; a curative package to trigger and/or accelerate cure of the oligomer(s) under appropriate cure conditions; and at least one polyolefin-based polyurethane that is not reactive under the cure conditions with the photo- and/or heat-curable polyolefin-based oligomer or the moisture-curable polyolefin-based oligomer. The present invention also relates to optical assemblies that include such optically clear adhesives.
