Abstract: Lenticular microstructures and methods of making the same is disclosed. The lenticular microstructures include composite lenticular microstructures having a first light transmissive polymeric layer, a second light transmissive polymeric layer, and an interface therebetween, wherein the first light transmissive polymeric layer has a first index of refraction, the second light transmissive polymeric layer has a second index of refraction, and the first and second indices of refraction have an absolute difference of at least 0.0002.
