Abstract
A light reflective film having a multi-layered structure including a light reflective membrane layer on a web. A plurality of transparent spherical glass beads are provided on the light reflective membrane layer. A transparent film layer is provided on the glass beads and is spaced away from the light reflective membrane layer by an air gap. A transparent coating encapsulates all of the component layers to form the light reflective film. The light reflective film is flexible and durable, and effectively reflects light when under water.
Claims22
A light reflective film, comprising:
- a light reflective layer;
- a plurality of transparent objects on the light reflective layer;
- a transparent film layer in contact with the plurality of transparent objects and spaced away from the light reflective layer by an air gap;
- and
- a coating layer covering the transparent film layer.
A retroreflective device, comprising:
- a web layer;
- a retroreflective layer on the web layer;
- a plurality of transparent objects on the retroreflective layer;
- a transparent film layer on the plurality of transparent objects and spaced away from the retroreflective layer by a gap;
- and
- a coating layer enclosing the web layer, the retroreflective layer, the plurality of transparent objects, the gap, and the transparent film layer.
A flexible light reflective device, comprising:
- a web layer;
- a light reflective layer on the web layer;
- a plurality of transparent beads on the light reflective layer;
- a transparent film layer in contact with the plurality of transparent beads and spaced away from the light reflective layer by an air gap;
- and
- a coating layer encapsulating the light reflective device.
A light reflective film, comprising:
- a light reflective layer;
- a plurality of transparent objects on the light reflective layer;
- a transparent film layer in contact with the plurality of transparent objects and spaced away from the light reflective layer;
