Abstract
Optically clear adhesive compositions contain an elastomeric polymer and a low molecular weight polymeric additive. The elastomeric polymer and the low molecular weight polymeric additive form an acid-base interaction. The refractive index of the adhesive composition is higher than the refractive index of the elastomeric polymer. The adhesive composition may also contain additional domains of liquids, polymers, additives or particles that have a higher refractive index than the elastomeric polymer.
