RETROREFLECTIVE SHEETING INCLUDING A SUBSTANTIALLY AMORPHOUS POLYMERIC LAYER |
摘要 |
The present application generally relates to retroreflective articles and methods of making retroreflective articles. The retroreflective articles include a substantially amorphous polymeric layer between the body layer and the discrete truncated cube corner elements. The substantially amorphous polymeric layer absorbs, dissipates, and/or accommodates at least some of the stress forces placed on the retroreflective article during processing. As a result, discrete truncated cube corner elements with increased fidelity can be formed. Consequently, retroreflective sheeting including a substantially amorphous polymeric layer has increased brightness compared to similarly made and composed sheeting lacking the substantially amorphous polymeric layer |
