Abstract:
1. A light-scattering composition, comprising a matrix polymer; diffuser polymer particles; wherein the diffuser polymer particles have an average particle size 0.8 to 0.9 μm; wherein the diffuser polymer particles comprise >4 wt % crosslinking density; wherein the diffuser polymer particles exhibit a different refractive index at a center thereof (RI wherein RI wherein the diffuser polymer particles are produced using at least one C wherein the diffuser polymer particles are single phase particles that exhibit a gradual change in refractive index from the innermost point to the surface of the particles; wherein the diffuser polymer particles are distributed throughout the matrix polymer; and, wherein the diffuser polymer particles comprise 0.1 to 10 wt % of the light-scattering composition.
