A light diffusing adhesive comprising a mixture of a pressure-sensitive adhesive matrix having a refractive index of n1 filled with organic, polymeric microparticles having a refractive index n2, wherein the absolute difference in the refractive indices of matrix and microparticles, that is, /Vn1-n2/V is greater than zero and typically in the range of 0.01 to 0.2. The weight ratio of matrix to microparticles, based on solids, is from about 1:1 to about 50:1, preferably from about 4:1 to about 25:1.
