Reema Chatterjee, a notable inventor based in Woodbury, MN, has made significant strides in the development of retroreflective sheeting technologies. With a remarkable portfolio of two patents, she continues to enhance the functionality and efficiency of retroreflective articles used in various applications.

Latest Patents

Chatterjee's latest innovations include two groundbreaking patents. The first patent, titled "Retroreflective Sheeting Including a Low Elastic Modulus Layer," focuses on methods of creating retroreflective articles. It features a body layer with an elastic modulus equal to or greater than 1750 MPa, along with truncated cube corner elements and a polymeric layer that has an elastic modulus of less than 1750 MPa. This innovative design improves the performance and efficacy of retroreflective materials.

Her second patent, titled "Retroreflective Sheeting Including a Substantially Amorphous Polymeric Layer," elaborates on retroreflective articles that utilize a substantially amorphous polymeric layer. This layer, positioned between the body layer and the cube corner elements, serves to absorb, dissipate, and accommodate stress forces during processing. This leads to the formation of discrete truncated cube corner elements with increased fidelity, ultimately resulting in retroreflective sheeting that boasts enhanced brightness compared to similar products.
