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.
光学透明的粘合剂组合物包括折射率至少为 1.48 的(甲基)
丙烯酸酯基共聚物和热塑性聚合物颗粒。其中至少有一些颗粒的平均粒径大于可见光的波长。粘合剂组合物是通过热熔加工包装粘合剂组合物制备的。
