Abstract

This invention relates to multi-layered optical films with enhanced functionality. It comprises a substrate, a stamping middle layer and a prism array on which forms a plurality of prism units. The upper layer of the prism array and the middle layer form a upper root and a cavity which may fit into each other tightly so as to produce an interlocked optical film. In addition, the present invention also provides a method of making the multi-layered optical films.
