Abstract
Adhesive compositions that are optically transparent include a (meth)acrylate-based copolymer having a refractive index of at least 1.48, and particles of a thermoplastic polymer. At least some of the particles have an average particle size that is larger than the wavelength of visible light. The adhesive compositions are prepared by hot melt processing packaged adhesive compositions.
