ARTICLE HAVING COMPOSITE LENTICULAR MICROSTRUCTURES AND METHOD OF MAKING |
| 摘要 |
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. |

1. An article comprising:
a light transmissive support layer having a generally opposed first and second major surfaces; and an array of composite lenticular microstructures disposed on the support layer, each composite lenticular microstructure comprising a first light transmissive polymeric layer having a first index of refraction and a second light transmissive polymeric layer having a second index of refraction, and an interface therebetween; wherein the absolute difference between the first refractive index and the second refractive index is at least 0.0002. |
