Abstract:
A stretchable reflective color-shifting film comprises a stretchable transparent polymer layer; a semi-transmissive metal layer; a transparent spacer layer; a reflective metal layer; an adhesive layer; and a stretchable base film layer. When the film body is stretched by 25%, the peak total reflectance stretched is at 80% of the peak total reflectance when the film body is unstretched according to the Total Reflectivity Test.
