  • Publication number: 20050058782
    Abstract: A decorative bow is provided having a plurality of loops of film. Each of the loops has an inner surface and an outer surface. The film has a transparent polymeric layer, a coating layer, a high refractive index layer and a colorant layer. The coating layer is disposed on a first surface of the polymeric layer. A plurality of embossed images are disposed within the coating layer. The high refractive index layer substantially covers the embossed images. The colorant layer forms the inner surface of the film bow loops upon final construction of the decorative bow and is disposed on either the polymeric layer or the high refractive index layer.
