Abstract: Safety window films are described. In particular, safety window films including a substrate including polyurethane—the substrate having a first and second major surface, an optically clear pressure sensitive adhesive, and a polymeric liner are described. The first major surface of the substrate is the top surface of the safety film, and the polyurethane has a Shore hardness of less than 80 D. Such films may provide improved physical and optical performance over conventional safety window films, while being easier to install.

Abstract: The present invention is directed an oriented, foamed article having an integral security element, and a method of making the article.
