Reflective sheet, articles made therefrom and methods of using same

摘要

A reflective sheet comprising a prismatic layer and a seal layer is provided. The prismatic layer comprises cells of prismatic projections surrounded by raised elements. The height of the raised elements is greater than the height of the prismatic projections. The seal layer is adhered to the raised projections. A space or gap is provided between the peaks of the prismatic projections and the seal layer. The seal layer comprises a crystalline polymer, a self-adherent polymer and an inorganic pigment. The seal layer acts as an adhesive layer to adhere the reflective sheet to a substrate. The self-adherent polymer is compatible with the crystalline polymer at a temperature equal to or higher than the melting point of the crystalline polymer. There is a high peel strength between the seal layer and raised elements. The reflective sheet is easily positioned on the substrate prior to it being finally adhered the substrate.
