Abstract

The present invention is an optically clear adhesive composition including a free-radically polymerizable acrylate or meth(acrylate) functional group oligomer, a trialkyl borane complex initiator, a photoacid generator, and a photosensitizer. A viscosity of the composition immediately after mixing and a viscosity of the composition about 24 hours after mixing changes by less than about 10%.
